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

I fix bugs in React, Next.js, 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.

You get 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.

What 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, and deployments that work locally and nowhere else.

Three years on production applications, much of it taking over codebases other people wrote. If a bug turns out to be a symptom of something larger, I will tell you rather than quietly billing you to paper over it.

This covers up to three bugs. Send me the repository or a description first and I will tell you what I think before you order.
