I need senior full-stack developers who can prove a substantial open-source record—specifically at least 300 merged pull requests on GitHub under your own name. The work spans web, mobile, and desktop initiatives, so versatility is key. The active tech stack includes JavaScript/TypeScript, Python, Java, .NET, Rust, and Go. Depth in two or more of those languages is mandatory because projects move quickly and switch contexts often. Share your Github repos that has over 300 + PR's and ensure no AI code are used and only human written code is written. Deliverables • Clean, well-tested code merged via GitHub PRs • Concise commit messages and inline documentation • Regular participation in review discussions Acceptance criteria • CI pipelines pass on every merge • Test coverage is maintained or improved • No new critical bugs introduced; technical-debt notes filed when discovered When you reply, send a link to your public GitHub profile showing the PR count (a quick screenshot helps) and highlight which of the listed languages you are most comfortable shipping production code in. I’m excited to see how your open-source experience accelerates our roadmap.

Your requirement for 300+ merged PRs signals you've been burned by developers who cannot navigate large codebases or collaborate at scale. The real risk here is onboarding someone who writes code in isolation and breaks your CI pipeline because they've never worked in a high-velocity team environment. Quick questions - what's your current test coverage baseline that cannot drop below? And are you running monorepo or multi-repo architecture, because that changes how I structure commits and manage cross-service dependencies? Here is the architectural approach: - GITHUB COLLABORATION: I maintain 400+ merged PRs across 6 production repositories including a fintech API handling 2M daily transactions and a healthcare dashboard serving 50K users. - POLYGLOT EXECUTION: I ship production code in Python (Django/FastAPI), JavaScript (React/Node), and Java (Spring Boot) with full CI/CD ownership from commit to deployment. - CI/CD DISCIPLINE: Every PR I submit includes unit tests, integration tests, and passes SonarQube scans before merge - I've never broken a production build in 3 years. I've led code review processes for distributed teams where a single broken merge costs $10K in rollback time. Let's schedule a 15-minute call to walk through my GitHub history and discuss how I'll integrate into your review workflow without slowing velocity.

Quick note on the GitHub ask before anything else most of my production work over the past few years has been under NDA for clients doing bug bounty and systems level engineering so it doesn't show up as public PR history the number you're asking for isn't something I can point to on a public profile honestly What I can show is ferrumnet a sans IO userspace TCP IP stack I built in Rust over a Linux TUN interface hand rolled async runtime six congestion controllers and a deterministic simulation harness for fuzzing and adversarial testing it's the kind of project most developers only ever read about rather than actually build from scratch and it gives a real sense of how I approach hard systems level problems even though it's one project rather than three hundred small ones Out of the languages you listed Rust is where I do my deepest work particularly anything performance sensitive or close to the metal beyond that I have strong hands on production experience in Python Java Go and NET across web mobile and backend systems and I move fast and confidently across all of them without needing much ramp up time If the 300 PR bar is a hard requirement I understand if this isn't the right fit but if you're open to evaluating on the paid code challenge directly I'd welcome the chance to show you firsthand rather than just tell you

Hello, I’m Fernando, a senior full‑stack engineer with a strong open‑source record and extensive experience across JavaScript/TypeScript, Python and Java. I see you need developers who can hit the ground running on web, mobile and desktop work while keeping the codebase clean and testable. Your emphasis on PR volume signals a focus on sustainable velocity; a team that treats each merge as a quality gate speeds up delivery and reduces technical debt. My approach is to start each feature in its own branch, enforce a strict CI pipeline, and write unit/integration tests that meet your coverage targets. By using the same language stack you already run, I avoid context‑switch overhead and keep maintenance simple, while the review process stays lightweight thanks to concise commit messages and inline docs. Recently I contributed over 350 merged PRs to an open‑source SaaS platform built with Python and React. The biggest challenge was keeping CI green while integrating a new payment provider; I added automated contract tests and reduced build time by 30%, which helped the team ship weekly releases without regressions. I look forward to proving the value of my open‑source experience on your code challenge and becoming a reliable contributor to your roadmap. Thanks

Handling 300+ PRs across multiple languages can cause merge conflicts when the same file is touched by both Java and Rust changes. I'd set up a pre-merge lint step that runs language-specific formatters and a small script to auto-detect overlapping changes before CI runs. That keeps the pipeline green and cuts review back-and-forth. A common pitfall is relying on a single test suite that only covers JavaScript, leaving Python and Go code unchecked. I’ll add language-specific unit tests and run them in the CI step so coverage stays high across all stacks. Ready to start immediately and tackle the code challenge as soon as you share it.
