About this gig
Something broken in your web app? A form that won't submit, an API returning 500, a React page stuck on loading, a deploy that fails? I find the cause and fix it, usually within 24 hours.

- Login and authentication issues (JWT, Auth0, sessions)
- Build and deployment errors on Vercel, Netlify, Render, and Railway
- Third-party API integration problems (OpenAI, payment, email)
What you get
- The fix, pushed to your repo or sent as a patch
- A short explanation of what caused it and how I fixed it
- Suggestions if I spot related problems
- Free follow-up if the same bug comes back within 7 days
How it works
1. Send me the error message, a screenshot or video, and repo access (GitHub) or a zip.
2. I confirm the price and time within a few hours.
3. I fix, test and deliver with notes.
I work as a backend developer on a production mobile app, so I debug real systems every day. Message me before ordering so I can confirm the fix fits the package.

FAQ
What do you need from me to start?
The exact error message, steps to reproduce it, and access to the code (invite RiyaGoyal716 on GitHub, or attach a zip). A live URL helps.
I only have one small bug. Do I need the Basic package?
Message me first. For a single quick fix I can send a custom offer at a lower price.
What if the bug cannot be fixed?
If I cannot fix it, I will explain why and you will get a full refund. You never pay for an unsolved problem.
Can you fix WordPress, PHP or Python bugs?
JavaScript, React, Node.js and MongoDB are my main area. For WordPress theme or JavaScript issues, yes; for deep PHP or Python work, message me first and I will tell you honestly if I can help.
