React & Python Expert Needed

I’m looking for a senior full-stack developer to fix and improve a small existing web app built with React (TypeScript) on the frontend and Python (FastAPI) on the backend.

This is a bug-fixing / stabilization task, not a full rebuild.

Scope includes:

▪ Fix frontend issues where UI does not refresh correctly after creating or deleting items
▪ Fix backend validation issues (bad input should return proper errors)
▪ Fix CORS configuration issues between frontend and backend
▪ Fix TypeScript warnings / console errors
▪ Ensure API calls and state updates work reliably
▪ Improve overall stability without changing the stack or rewriting the project

Nice to have:

▪ Experience with FastAPI best practices (Pydantic validation, error handling)
▪ Strong React state management and debugging skills
▪ Clean code and quick delivery

Goal:

Make the app fully functional, stable, and working smoothly with no manual refresh needed.

Please share:

▪ Similar bug-fixing experience
▪ Your approach to debugging full-stack issues
▪ Estimated timeline

Looking for someone reliable and efficient who can deliver a clean fix quickly.
