Sobre este Serviço

Stuck on a bug you can't crack? Send it to me I'll find the real cause and fix it properly, not with a band-aid.


I'm a full-stack developer who fixes bugs and errors in:

  • React / Next.js hydration, state, rendering, UI issues
  • Node.js / Express and Python / FastAPI backend, APIs, database
  • TypeScript / JavaScript build and deployment errors


WHY TRUST ME

  • 35+ bug fixes merged into major open-source projects: React Router, ESLint, Axios, Node.js and Jest. Finding the root cause in an unfamiliar codebase is literally my main skill.
  • On a recent client platform I found a billing bug that would have charged every customer 100x the correct amount fixed across their frontend and backend, delivered three days early.
  • I built and maintain an AI-powered platform, "NSU InSights" used by 4,000+ students, solo.


WHAT YOU GET

  • The bug fixed and fully tested
  • A clear explanation of what actually caused it
  • Clean code that matches your existing style


HOW IT WORKS

Message me your repo or code and what's broken screenshots or error logs help. I'll confirm the scope and timeline in writing before you order.
