I will fix bugs and errors in your react, nextjs, node or nestjs app

Something is broken and you need it working, not rewritten.

I fix bugs in React, Nextjs, Node, NestJS and Express applications. Front end or back end, whichever side it is actually coming from, which is often not the side it appears on.

What you get is a fix at the root cause, not a patch that hides the symptom until next week. With every delivery I send a short written explanation of what was actually wrong, so you or your next developer are not guessing later.

Things I handle regularly: API calls failing or returning the wrong shape, authentication and session problems, database queries that are slow or returning duplicates, state that will not update, forms and validation misbehaving, builds that fail only in production, payment webhooks not firing, deployment issues where it works locally and nowhere else.

I have spent three years on production applications, including taking over codebases written by other people, which is most of this work. I will tell you honestly if a bug is a symptom of something larger rather than quietly billing you to paper over it.

Send me the repository or a description and I will tell you what I think before you order.
