    I’m ready to bring in an experienced ethical hacker to run a thorough security audit of our production web application. You’ll have gray-box access—enough credentials and limited architecture notes to work efficiently, but not full source code. Key focus areas are clear: • Robustness of user authentication and authorization flows • Protection of data at rest and in transit • Security posture of every third-party integration we rely on I expect a blend of manual and automated testing (Kali Linux, Burp Suite, OWASP ZAP or similar) aimed at uncovering the full OWASP Top 10 spectrum. A secure-configuration review of servers, middleware, and relevant cloud services should run in parallel. Where you discover a critical issue, please include an exploit...

    I need an experienced engineer to take WAN—or an equally capable open-source alternative—and install it from end to end on my server. You are free to pull the code directly from GitHub or choose a more streamlined source if that speeds things up; what matters is that the final environment is clean, stable, and reproducible. Here’s what the engagement looks like: • You assess my current server specs (Linux, Windows, or macOS—happy to adapt) and confirm all prerequisites. • You handle every step of the build: dependency fetching, compilation, configuration, and service hardening. • Once running, you verify that the application launches on boot, logs correctly, and exposes the expected web or CLI interface. • You finish by handing over concis...

The job covers the full hand-off: pulling the code and data from the Emergent environment, configuring every dependency on the server, and confirming the app starts cleanly under my domain. ### Deployment Files Ready: - ✅ `` - Complete guide for IT person - ✅ `` - Deployment documentation --- Success means that, once you’re done, I can visit the live URL and see the app performing just as it did on Emergent, with logs clean and restart behaviour solid. If additional configuration files, environment variables, or one-off commands are required, include them in a short README so I can reproduce the setup later.

The target machine hasn’t been finalised, so let me know which OS you’re most comfortable with (Windows, Linux, or macOS) and any prerequisites you would expect to install first.

    I have a working Med-tech web portal hosted on Replit that now needs to live in AWS. The core codebase is stable, but the project has reached the point where I need two things done in one seamless hand-off: • First, migrate the application to AWS, setting up everything required for a secure, scalable deployment—think EC2 (or container services if that suits the code), an HTTPS-enabled load balancer, automated backups in S3, and a simple CI/CD pipeline so pushes to the main branch redeploy cleanly. • Second, extend the product by adding new features while keeping the look and feel mostly intact. Only minor UI tweaks are expected; the layout, color palette, and overall style can stay. I’ll outline the exact features after we sign an NDA, but they sit in the usual Med-...

Sub-domains are already pointed; I simply need a clean, secure deployment that sticks to standard ERPNext modules—no customisation or code tweaks at all. You’ll log in over SSH, install required packages (Python, Node, Redis, MariaDB, Nginx, Supervisor), use bench to create separate sites for ERPNext and Frappe Mail, secure everything with Let’s Encrypt SSL, and confirm that incoming and outgoing email flows without hiccups. A concise hand-over that shows how to update, back up, and restore the stack will round things off. Deliverables • Working ERPNext and Frappe Mail sites on my Linux server, both served over HTTPS • Script or commands used, so I...

    UniFi VLAN & iPad Fix -- 2
    4 days left
    Verified

    I run a small UniFi network that serves a local WebRTC page hosted on our own server. The page opens instantly on my laptop, yet my iPads refuse to load it at all—even though they are on the same Wi-Fi. Alongside that, Wi-Fi quality on the iPads swings from excellent to poor for no clear reason. The site must be reachable this weekend, during European daytime hours, so I need a UniFi-savvy network admin who can jump in promptly, review the configuration, and correct whatever is blocking traffic to the tablets. Context you’ll step into • Current issue: the iPad shows “page not loading at all.” • VLAN status: I’m not sure the settings fully cover the iPads. • Hardware in play: – UniFi Access Points – UniFi Switches ...

    My OVH-hosted Linux VPS was taken offline after a phishing abuse report and is now in Rescue mode. OVH will not clean the server, so I need an experienced Linux sysadmin to fully recover it. Important: This server hosts approximately 300 WordPress websites. Recovering these sites is critical. Full data loss is not acceptable unless recovery is proven unsafe. What I need: Access the server in Rescue mode and remove all malware, backdoors, and malicious cron jobs. Take a safe backup of all legitimate WordPress sites and databases. Rebuild the VPS on a fresh OS and restore only clean data. Secure the server (SSH hardening, updates, basic firewall). Ensure the machine is clean so OVH can lift the abuse/quarantine. Rescue-mode root SSH access and the OVH abuse ticket are ready to share....

    I’m a DevOps / Cloud Engineer juggling several fast-moving projects on AWS and the workload has outgrown a one-person bench. I want an experienced partner who can drop straight into my day-to-day flow and help me turn tasks around faster while keeping quality high. Your focus areas will mirror mine: designing and refining CI/CD pipelines, writing and maintaining Infrastructure-as-Code with Terraform, and managing the full AWS stack that powers our services. Expect hands-on DevOps engineering and cloud computing work—everything from automating software deployment to troubleshooting build failures or tweaking IAM policies for tighter security. I frequently lean on GitHub Actions, Jenkins, Terraform Cloud, EKS, Lambda and CloudFormation, so fluency with those (or similar) tools w...

    I’d like a feature-complete, upstream-ready Linux kernel driver for the Logitech RS50 that exposes every output and input capability the device offers. Autodetect the wheel as soon as it is plugged in, create the correct device nodes and present clean, descriptive udev properties so userspace apps immediately recognise it. I have an RS50 on hand for testing and can run any diagnostics or custom binaries you provide while we iterate. Let me know your expected timeline and which kernels you plan to target first. There may be a repository which can be a useleful starting point:

    I need a concise Python tool that, after I type in a number, reaches out to , fetches the current balance, and prints (or returns) the amount in a clean JSON or plaintext format. The hurdle is DataDome: the request must look like it comes from a real browser, survive the cookie / token dance, and continue working even when the site rotates user-agent fingerprints or starts rate-limiting by IP. In practice that means the script should automatically: • open each session with a believable, ever-changing user-agent string • recycle or tunnel the connection through proxies when an IP is flagged • preserve and replay the anti-bot tokens issued by DataDome so the check actually succeeds All inputs will be manual I’m happy for you to lean on whatever stack you think bes...

    AWS Account Strategy & Setup Create multiple AWS accounts (recommended for security and operational isolation) — one per environment if possible (e.g., dev, staging, prod). Properly set up networking in the new account(s): VPCs, subnets, security groups, VPNs (or Direct Connect if needed) — this is a priority improvement requested previously. Infrastructure Provisioning Rules All infrastructure (servers/EC2, S3 buckets, RDS databases, etc.) must be created using existing CDK stacks — no manual creation allowed. Deploy and adapt CDK stacks to the new account(s)/environment(s) as needed. Domain & DNS Migration (Critical – Involves Downtime) Delegate DNS by updating nameserver (NS) records at the registrar to point to the new AWS Route 53 Hosted Zone(s) in th...
