About this gig
Your app is broken and you need someone who actually knows what they're doing, not someone who'll guess their way through it.
I debug React, NextJS, NodeJS, and TypeScript applications every day. I've worked on production platforms serving 800,000 users across 100 countries, so I've seen bugs at every level of complexity.
What I fix:
React and NextJS hydration errors, SSR problems, broken routing, state bugs, API issues, infinite re-renders, and memory leaks.
NodeJS and Express server crashes, auth failures, database connection errors, async bugs, and middleware problems.
TypeScript type mismatches, compilation failures, interface errors, and strict mode issues.
Third-party integrations: Stripe, Firebase, MongoDB, PostgreSQL, OAuth, and REST APIs.
How I work:
You share the code via GitHub, ZIP, or screen share. I diagnose what's wrong, explain it clearly, fix it, and walk you through what I did.
No vague updates. No disappearing. No fix that breaks something else.
5-star rated. Send me your bug details and let's get your app working again.
