About this gig

Your React or Node.js app has a bug you can't track down, or a small feature you need added? I'm a full-stack developer who spends his days reading other people's production code, finding the cause from logs and fixing it without breaking what works.


I can help with:

- React / TypeScript front-end bugs (state, rendering, forms, routing)

- Node.js / Express API errors, authentication and database problems

- Firebase (Auth, Firestore, Hosting) issues

- Payment and API integrations (Stripe and mobile money)

- Small features added to an existing code base


What you get: the fix, a short explanation of the cause, and a note of the files I changed, so your team can follow.


Send me repository access (a branch is enough), the error message and the steps to reproduce it.
