About this gig
Got a React or Next.js app that has bugs, needs a new feature, or just needs a senior pair of hands? I fix and build cleanly, fast, and without breaking what already works.
I'm a senior engineer with 498 orders, 100% satisfaction, and 8,700+ hours on production apps. I work in React, Next.js, TypeScript, and the modern frontend stack (Tailwind, Redux, React Query, shadcn).
What I do:
- Fix bugs and layout or state issues at the root, not with band-aids
- Build new pages, components, and features to match your design
- Connect your frontend to APIs, auth, and databases
- Clean up and refactor messy or AI-generated React code
- Clean commits on your repo, so you own everything
Whether it's one stubborn bug or a full feature, message me what you need and I'll recommend the right tier.

FAQ
How fast can you start?
Usually within 4 to 12 hours if the repo or snippet is accessible. Premium gets priority same-day.
What if you can't reproduce the bug?
I investigate first. If I genuinely can't diagnose it, I refund. I only charge when I can fix it.
Do I own the code?
Always. I push to your GitHub or send a patch file. No lock-in.
Can you fix multiple unrelated bugs?
Standard covers up to 3 related bugs. For many unrelated bugs across modules, message me for a custom offer.
Do you write tests?
Standard and Premium include a regression check on the affected flow.
