I’m building an end-to-end travel platform and need help turning the concept into a working system that covers three distinct user groups: travellers, drivers, and myself as the administrator. USER-FACING WEBSITE Travellers must be able to create an account, log in securely, enter the details of an upcoming trip, and later see every past journey in a neatly organised Trip History screen. Push notifications will keep them informed of booking confirmations or schedule changes. ADMIN DASHBOARD (WEB) From a dashboard I want to publish available vehicles directly to the user website, keep operator records up to date, and read every enquiry that comes in. When an enquiry needs follow-up, I’ll decide which operator receives it and push it to that operator's inbox in real ...

My current web-scraping pipeline is functional but slow, and the data-processing stage in particular is exhausting the GPU. I want to cut total runtime, shrink GPU memory consumption, and have every run automatically log its own performance so I can measure gains over time. You’ll start by profiling the existing Python code (pandas, NumPy, CUDA-accelerated routines), pinpointing the true hotspots. From there, I need refactored or parallelised logic, smarter batching, and any lightweight caching that prevents redundant computation. I’m open to revisiting earlier extraction steps if a quick tweak there will compound the speed-up, but the main brief is processing-level optimisation. Deliverables: • Optimised processing script(s) with clear inline comments • A small...

I need a simple yet reliable WhatsApp bot that tracks specific GIFs shared in one or more group chats and keeps a running total for each participant. Whenever Helen drops eight GIFs and James uses nine, those figures should flow straight into a clean CSV file so I can open it in Excel or import it elsewhere without any extra formatting work. The Specific gif needs to be able to be set by me, i need to be able to set the gif that the script is looking for because it will change. The core functions are straightforward: • Detect a message that contains a specific GIF • Attribute the GIF to the correct sender. • Append or update that user’s running total in a CSV file with columns for user name (or phone number), total-to-date, and a timestamp of the update. Pleas...

I need a web-based AI platform that can take over the entire appointment–setting flow for clients in multiple industries. At its core the system should read a prospect’s availability, negotiate a suitable time slot, and confirm the meeting without human intervention. What matters most to me is that the solution operates as a true SaaS web application, able to plug into popular calendar ecosystems (Google, Outlook, iCloud, Office 365) and then handle both inbound requests and intelligent outbound calls. The voice component must sound natural, handle common objections on the fly, and lock in a meeting inside the prospect’s calendar. Think of a friendly, self-learning call agent that knows when to push, when to pause, and when to pivot to alternative times. Key deliverab...

I have a multichain, non-custodial wallet running on Android and the next milestone is to add support for a brand-new blockchain that is not yet included in common libraries such as WalletCore or Web3j. The current app is written in Kotlin with a bit of Java, built in Android Studio, and already handles several EVM and non-EVM networks. Your task is to wire the new chain into the existing architecture so that users can create addresses, view balances, sign and broadcast transactions, and see their history exactly as they do with the other networks in the app. You will be working with my existing Git repository, where the wallet logic, key management, and UI layers are cleanly separated. The custom chain exposes standard JSON-RPC endpoints; any additional SDK work that may be required sh...

I’m ready to turn my Jayah Lee concept into a dedicated Android application and need a skilled developer to make it happen. The goal is a stable, well-structured APK that I can publish to Google Play. Here’s what I’m looking for: • End-to-end Android development—from setting up the project and integrating any required APIs to delivering a fully tested build. • Clean, maintainable Kotlin or Java code that follows Android best practices and Material Design guidelines. • Basic UI/UX aligned with the Jayah Lee brand (I’ll share branding assets once we start). • Clear documentation so I can maintain or expand the app later. If you have a solid track record in mobile app development and can guide me through launch, I’d love to hear ...

I’m ready to launch an e-commerce experience on Android and need a developer who can take the project from first commit to Google Play release. The core of the job is building a native Android app that lets shoppers browse a structured product catalog, add items to cart, and complete secure check-out.

I need my Oracle APEX page to update itself so the tablets on our shop floor always show live data without a manual reload. The page’s focus is on real-time user interactions—specifically new page views. Every time a fresh view arrives the screen must refresh seamlessly and play a brief audible cue to alert nearby staff. Please wire the refresh logic (Dynamic Action, JavaScript polling, or another APEX-friendly approach) so the page checks for new records and renders the latest state automatically. When the event is detected the tablet should emit a short sound that works on both Android and iOS browsers, respecting their autoplay policies. Deliverables: • Working APEX page (or clear code snippets) that auto-refreshes on new page views • Audio trigger integrated w...

I need an Android application that lets end-users purchase a local virtual number and instantly configure it from their phone. Inside the app the user must be able to set up call forwarding, manage voicemail greetings and messages, and send/receive SMS—all tied to the same newly purchased local number. The flow I have in mind is straightforward: after sign-up, the user browses available local numbers (pulled from a telecom API such as Twilio, Plivo, Telnyx or a comparable SIP provider), buys one, and then sees three configuration screens—Call Forwarding, Voicemail. Changes should apply in real time via the provider’s REST endpoints or SIP signalling. Please build the client in Kotlin, follow an MVVM structure, and use native Android components (no WebView shortcuts). A ...

I need a complete, beginner-friendly training program that takes absolute newcomers and turns them into job-ready practitioners across three pillars of modern machine learning: Natural Language Processing, Computer Vision, and Predictive Analytics. Everything must be delivered through live online sessions so students can ask questions in real time and work through hands-on exercises as a group. Here’s what I’m expecting from you: • A structured curriculum that steadily builds from zero knowledge to employment-level competence in each focus area. • Live session slide decks, annotated notebooks or scripts, and any datasets you plan to use, shared ahead of each class. • Practical projects after every major module so learners leave with portfolio-worthy work. ...

I'm building a new business-services platform and need end-to-end development help: polished React screens on the front, a solid Node.js API at the back, and a well-structured MySQL data layer tying everything together. The job spans UI/UX design through deployment. You’ll take wireframes and shape them into a modern, responsive interface, weave in secure user flows (contact forms, service pages, an admin dashboard), and keep performance, accessibility, and basic SEO in mind throughout. Clean, well-commented code, sensible component architecture, and Git-based version control are non-negotiable. For the backend, the brief is a RESTful (or GraphQL if you prefer) Node.js service written in expressive, testable JavaScript/TypeScript. Expect authentication, role-based permission...

An internal Android APK needs a complete manual QA pass before it moves to the next release gate. The build is not yet in any store, so access will be shared privately once the engagement begins. Scope • Build structured, step-by-step test cases that cover core flows, edge conditions, error handling and user-level settings. • Execute those cases across at least one real Android phone and, if available, an emulator to surface OS-level quirks. • Focus on the visual layer first: layout consistency, touch targets, typography, dark/light mode behaviour and orientation changes. • Probe performance: launch time, screen-to-screen latency, scrolling smoothness and memory spikes. Simple profiling via Android Studio, adb or similar is welcome but not mandatory—cle...

Project Description: WhatsApp Lead Generator + Outreach Automation (Google Maps → WhatsApp Web) 1) Goal of the Project Build a marketing application that: collects business leads from Google Maps (based on a target market), organizes and filters those leads, automatically sends personalized WhatsApp messages using WhatsApp Web, tracks replies and qualifies leads using AI, outputs a clean list of “Qualified / Not Qualified / Follow-up needed”. This system is intended for outreach to businesses found on Google Maps (e.g., restaurants, clinics, salons, workshops, etc.) in specific locations and categories. 2) What the App Must Do (Core Workflow) A) Lead Collection from Google Maps User selects: Business category/keywords (example: “dentist”, “gym&r...

I’m building a new Android-only social networking app whose standout feature is strong, built-in user safeguards. The first release doesn’t need every bell and whistle; what matters is that people can interact normally while staying protected by the following controls: • User blocking – a single tap must hide all content and prevent further contact. • Usage time limits – daily caps stored server-side so a reinstall can’t reset the clock. • Content restrictions – category filters that keep unwanted posts out of feeds and search. If you can deliver that foundation along with a basic sign-up/login flow and a lean feed UI, we’re good for the MVP. I’m happy with Kotlin or modern Java and standard Jetpack components; alternate...

Looking for part time work into java and spring boot development as programmer. Happy to learn html and execute project with someone on hourly or daily basis

# ONLY APPLY IF PRIOR EXPERIENCE # NO EXPERIENCE = DIRECT REJECTION Need to develop and end-to-end ESIM APP with end to end integration The core experience must let users activate or deactivate an eSIM in a tap, monitor real-time data consumption, and juggle several profiles at once without friction. Everything has to feel native—Swift or Objective-C on the Apple side, Kotlin or Java for Android—while remaining anchored to GSMA standards, eUICC requirements, and the latest carrier APIs we’ll integrate. Security is non-negotiable. All traffic and stored credentials need strong, device-level encryption, and I want biometric login (Face ID, Touch ID, or Android equivalents) so users never see a password screen after the first launch. Token-based sessions, secure keych...

I run United Softech, a training institute in Salem, Tamil Nadu, and I want a part-time Java trainer who is willing to teach from our classroom—not over Zoom, Meet, or any other online platform. You’ll be guiding small batches of working professionals, so the explanations need to be crisp and practical. We cover both Core and Advanced Java, from OOP fundamentals right up to collections, JDBC, and basic frameworks, so you should feel at ease moving across that spectrum. Even if your formal teaching experience is less than a year, that’s perfectly fine as long as you can convey concepts clearly and handle real-world questions. Timings are flexible; we can decide mutually convenient slots and will settle payment on a per-hour or per-session basis. Key points you must mee...

I need our existing Android app to talk smoothly to a Bluetooth thermal printer and, while you are in the code, refresh the look of one key report. Integration first: the app must discover, pair with, and print to a standard 58 mm or 80 mm Bluetooth unit. I’m open to the usual brands—Epson, Zebra, Brother—as long as the final APK prints reliably and reconnects automatically after the first pairing. Raw ESC/POS commands or an official SDK are both fine; pick whichever gives the fastest, most stable print. Report revamp next: the data is already there, but the current layout is cramped and hard to read once printed. I want cleaner spacing, clearer section headings, and a hierarchy that looks good on both the in-app preview and the physical slip. No new calculations are...

I have a small web application built with the PERN stack that has a reproducible bug affecting data flow between the API and the frontend. The issue occurs when fetching and displaying records from PostgreSQL. The API responds, but the UI does not behave as expected in certain cases. This is a debugging task only — no new features, no redesign, and no large refactors. Scope of Work: - Investigate the API ↔ frontend interaction - Identify the root cause (query, API logic, or React state handling) - Apply a minimal, correct fix - Verify the issue is fully resolved Good Fit If You: - Have real experience with PERN or MERN-style stacks - Are comfortable debugging backend queries and frontend state Prefer short, focused tasks

I’m providing a zipped Java code base that uses Maven. All I need is for you to import it into IntelliJ IDEA, resolve any build issues, and confirm that it compiles and runs from the IDE with the default Maven configuration—no extra plugins or dependencies required. Once it’s working, return the updated project (or the .idea folder) along with a concise step-by-step note so I can recreate the setup on my own machine. If unit tests are present, please make sure they pass inside IntelliJ as part of your verification. That’s the entire task; looking forward to getting this running smoothly.

I’m upgrading my platform to process transactions through a dedicated blockchain gateway so every payment that passes through the system is cryptographically verifiable and tamper-proof. The job covers designing the gateway architecture, selecting an appropriate chain (Ethereum, Polygon, BSC or another you can justify), building or customising smart-contract code if that proves to be the simplest route, and exposing clean REST/JSON or Web3 interfaces my front-end can call. The core success metric is end-to-end security: a user initiates a payment on the site, the request reaches the gateway, the transaction is written on-chain, and I receive an instantly checkable hash I can surface back to the user. Performance must remain within normal web-app latency, and the code needs to be cle...

I need my Samsung Galaxy A07 safely rooted so I can spoof the phone’s GPS and clock in to our attendance system from different sites. I haven’t tried any rooting method before, but I’m ready to move forward and fully accept the warranty risk. I already know which mock-location app I want to use once root is confirmed. Here’s what I’m looking for: • A proven, repeatable rooting method for the A07 (Android 11) that unlocks the bootloader, flashes the required files, and installs Magisk or an equivalent solution so root can be toggled and hidden when necessary. • Post-root configuration that lets my chosen GPS-spoofing app run flawlessly without the attendance app detecting root or the mock location. • Clear, step-by-step instructions (video o...

I need a lean yet reliable mobile video-chat application built specifically for Android. The core requirement is smooth, real-time video calling, complemented by an in-call text chat so users can exchange short messages while they talk. Scope • Native Android build or a robust cross-platform framework that compiles cleanly to Android. • WebRTC, Agora, or a comparable SDK for low-latency video and audio. • Simple user flow: register / log in, see contacts, start or receive calls, chat during the session. • Basic UI—functional and intuitive is enough; eye-catching design can follow later. Deliverable An installable APK (and source) that lets two Android devices connect, hold a stable video call, and send text messages in the same screen. Please include cle...

I have an existing Android app that’s suddenly showing its rough edges: a few interface glitches, some broken functionality, and—most urgently—the Razorpay payment flow has stopped completing transactions. I need a developer who can dive straight into the Android Studio project, diagnose the underlying causes, and push a clean, tested patch back to me. Here’s what success looks like for me: • All identified UI irregularities are ironed out across common screen sizes. • Core features that are currently returning errors or behaving unpredictably work reliably after your fix. • Razorpay SDK is updated or re-configured so users can finish a purchase without any failed or hanging payments. • You verify the fixes on at least Android 11 and 13...

I need a reliable developer to turn my concept into a polished Android app. I already know I only want it on Android for now, so please focus your proposal on native Android solutions—Java, Kotlin, or a well-maintained cross-platform framework compiled specifically for Android are all fine by me. I have the core idea sketched out but will rely on you to translate those requirements into clean UI, efficient back-end logic, and a smooth user experience. Code should be well-documented and handed over with clear build instructions along with the final APK. In your response, let me know: • the tech stack you prefer for Android • a concise timeline with major checkpoints (design draft, first build, testing, final hand-off) • examples of previous Android apps you built that...

I need a complete guard-tour solution that lets several independent client companies run their patrols from one shared system. On the web side I will create companies, upload sites, generate QR checkpoint tags and assign guards or supervisors. The Android companion app must let each guard sign in quickly with a one-time SMS code tied to their mobile number (no email/password). When they reach a checkpoint they scan the QR code, the app grabs their GPS coordinates in real time and syncs the hit straight back to the web dashboard. Guards can also file an incident on the spot, attaching photos, notes or voice if possible. Because the platform will be shared by multiple companies, roles and data must stay completely isolated—managers only see their own guards, sites, reports and inci...

About Intugine: Ever wondered how the physical goods we consume every day (think dairy, snacks, or your favorite choco chip ice cream) reach you in time? Or how beautiful furniture or sophisticated electronic equipment and gadgets you use are delivered in the best possible condition at your doorstep. Their journey spans from getting sourced, manufactured, and stored, to getting moved across a highly intricate supply chain network across the globe before it gets delivered. Global brands constantly face challenges like not having visibility of their raw materials, which delays production and in turn, delays customer shipments, or tracking shipments across various modalities and multiple geographies. Intugine Technologies is one of the most trusted solution partners catering to these brand...

I want to bring a brand-new social networking idea to life on Android. The concept, user flows, and core screens are already sketched; now I need a developer who can turn them into a polished, production-ready app. Here’s the outline of what I’m after: • Full Android build in Kotlin (Java is acceptable if you have strong reasons). • Standard social features—secure sign-up/login, user profiles with photos, a simple post feed, likes/comments, and real-time chat or messaging. • Cloud-based back-end: I’m leaning toward Firebase for authentication, Firestore/Realtime Database, and push notifications, but I’m open to alternatives if you can justify them. • Clean architecture, modular code, and clear naming so another dev can jump in later if nee...

I’m looking for an experienced Kalipso Studio developer to build an Android app whose first goal is simple: let warehouse staff count and record stock quickly and accurately. The initial milestone is an MVP that: • Opens straight to a clean “New Count” screen. • Lets users add items manually or by barcode scan (ZXing or Kalipso’s native scanner component). • Saves each entry—item code, description, quantity, date/time—locally and sync-ready. From there, I want to grow the app in short, progressive sprints. Next stages will include: – Role-based access (admin, supervisor, custom roles I can create myself). – Basic history view so I can review past counts. – Optional cloud sync / simple report export when w...

I’m building a full–stack Android finance app that lets users deposit funds straight from their Binance account, track every investment they make, and review portfolio performance at a glance. The core flow is simple: sign up with email and password, link Binance through the official API, move funds into the in-app wallet, and then watch positions update automatically. Here’s what I need from you: • Android front-end that feels native and responsive, guiding the user from authentication through deposit and into their personal dashboard. • Secure back-end (cloud-hosted) that saves user profiles, encrypted API keys, and all transaction data, with clean REST endpoints ready for future expansion. • Binance API integration focused on deposits and balance l...

I’m looking for a specialist experienced with affiliate programs such as Amazon, Nike, Adidas, H&M, ASOS, and other fashion brands. I already have a working app called FitFindAI, an AI-powered platform for finding clothing and creating outfits from photos and text. The goal is to help get approved by affiliate programs, choose the right application strategy, and integrate affiliate links (deep linking) into the app. Experience with affiliate networks (Impact, Rakuten, Sovrn, etc.) and e-commerce or mobile apps is important.

I’m building a public-facing portal that stores and presents policy information in a clear, searchable format. The site’s primary purpose is informational, yet it must go a step further by letting an integrated AI layer extract meaningful data analysis and insights from the underlying content. ***Please note this the below is an idea for now, I am totally open to something basic that hits most of these boxes as a start to help me visualize it. And could hopefully be the basis for future collaboration and depth going forward. At a glance, here’s what the finished product should achieve: • Store policies and their details in a well-structured, scalable database for a client. • Offer client a fast, intuitive interface to browse, filter, and compare policies by c...

Core System Objectives: Multi-Tenant Architecture: Isolated accounts and data for each end-client (company). Orchestration & Control: Centralize business logic and act as t...

I want to kick-start an Android application and the very first milestone is a rock-solid user-login flow. Think of it as the foundation on which I’ll later build revenue-generating features, but for now the scope is tight and focused: • A clean Android project written in Kotlin (Java is fine if you strongly prefer it) that opens with a modern sign-in / sign-up screen. • Secure authentication—email & password at minimum, with token-based session handling and a straightforward password-reset step. • Simple, intuitive UI that’s easy for me to re-brand later. • Clear, well-commented code plus a short README so I can compile and run the project without guesswork. Feel free to lean on Firebase Auth, a custom REST back end, or another proven sol...
