About this gig

Is your Next.js, React, or Node.js app throwing errors you can't figure out? I'll find and fix the bug fast.


I specialize in:

- Next.js 15 App Router issues (routing, server components, middleware)

- Supabase auth and database errors

- Stripe integration bugs (webhooks, checkout, subscriptions)

- TypeScript type errors and build failures

- Vercel deployment issues

- React state bugs and performance issues


How it works:

1. You share your repo (GitHub/GitLab) or the relevant code

2. You describe the bug and expected behavior

3. I fix it, test it, and explain what was wrong


I've shipped production SaaS apps with this exact stack I know where things break.


Please message me before ordering if your bug is complex or you're unsure which package fits.
