About this gig

Are generic errors and API failures slowing you down?

I am a Full-Stack MERN Engineer with a rigorous background in Systems Programming (C++/Linux). I don't just "patch" code; I use deep-level debugging to find the root cause and fix it permanently.

I specialize in fixing:

React.js Issues:

  • "White Screen of Death" & Rendering loops
  • Hooks errors (useEffect, useMemo)
  • State Management (Redux/Context) & Props issues

Node.js & Backend:

  • Server crashes & 500 Internal Server Errors
  • Authentication logic (JWT, OAuth, Passport)
  • Middleware & Routing failures

API & Network:

  • CORS errors & Proxy configuration
  • Failed Axios/Fetch requests
  • Async/Await & Promise rejection handling

Database:

  • MongoDB connection failures
  • Mongoose Schema & Validation errors

Why hire a Systems Engineer? My low-level C++ & Memory Management background means I understand the architecture better than the average developer. I fix the bug AND explain exactly why it happened so you don't repeat it.

Tech Stack: React.js, Node.js, Express, MongoDB, Tailwind, TypeScript, Docker.

PLEASE MESSAGE ME BEFORE ORDERING Every bug is unique. Please send a screenshot of the error or a code snippet so I can confirm the fix immediately!
