About this gig

Stuck with a broken layout, API error, or backend code that refuses to run? Don't waste hours debugging - I am here to fix it fast.


I am a software developer specializing in React, Node.js, and Python (FastAPI). I will audit your code, find the root cause of the issue, and deliver a clean, working solution with a quick turnaround.


What I can fix for you:

- React & Frontend: State management issues, responsive design flaws, Tailwind CSS bugs, broken hooks, and rendering errors.

- Backend & API: FastAPI or Node.js crashes, broken routes, authentication/JWT failures, and database connection issues.

- Runtime Errors: Resolving tricky JavaScript/TypeScript or Python exceptions.


My Technical Stack:

- Frontend: React.js, JavaScript, TypeScript, Tailwind CSS.

- Backend: Python (FastAPI), Node.js, Express.

- Databases: PostgreSQL, MongoDB, Firebase.


How it works:

- Message me and share your repository, code snippet, or error log.

- I analyze the issue and estimate the time.

- I fix the bug and send you the working code.


Please contact me before ordering so we can check the error together first!
