About this gig

Is your API not working the way it should?

I will quickly find and fix issues in your backend, API, or integration so you can move forward without wasting hours debugging.

I can help with:

  • API errors (500, 400, unexpected responses)
  • Authentication issues (JWT, OAuth, sessions)
  • CORS problems
  • Broken endpoints
  • JSON formatting issues
  • Third-party integrations (Stripe, REST APIs, etc.)
  • General backend debugging

What you get:

  • Fast diagnosis of the issue
  • Clean and working fix
  • Explanation of what went wrong
  • Suggestions to prevent future issues

Tech stack:

Node.js, Python, REST APIs, Express, FastAPI, and more

If you're unsure, just message me before ordering and I will guide you.
