About this gig
Is your app crashing, showing errors or not working the way it should? I'll find the real cause and fix it properly, not just hide the symptom.
I fix bugs in:
React and Next.js (UI, state, routing, hydration and build errors)
Node.js, Express and NestJS APIs (500 errors, auth, database queries)
Flutter apps (crashes, layout overflow, Firebase, state management)
Deployment issues on Vercel, AWS and Docker
How it works:
1. Send me the error, a screenshot or a short screen recording
2. I reply with what's wrong and which package fits
3. I fix it, test it and explain what changed
What you get:
Root-cause fix with clean, commented code
Tested on your setup before delivery
A short explanation so it doesn't happen again
7 days of free support for the same issue
Not sure which package fits? Message me with your issue and I'll reply quickly with an exact quote.
