About this gig

Having issues with your React app or Node.js backend?


I help quickly debug and fix bugs, errors, and broken functionality in existing web applications. Whether its a frontend issue, API error, or backend crash I can jump in and solve it.


What I can fix:

  • React errors, UI bugs, broken components
  • Node.js / Express API issues
  • Authentication problems (JWT, sessions)
  • Database errors (MongoDB, queries)
  • API integration issues
  • Performance and loading problems

I focus on finding the root cause and fixing it cleanly, not just patching the issue.


Send me the error or details before ordering Ill take a quick look and guide you.
