About this gig
Frontend Developer with 7+ years of commercial experience in React, Next.js and TypeScript. I fix bugs other developers gave up on.
NO FIX NO PAY. If I can't solve it, you get a full refund.
WHAT I FIX
- React/Next.js: broken hooks, state issues, hydration and rendering errors
- JavaScript/TypeScript: logic bugs, API errors, console warnings
- CSS/Tailwind: layout shifts, responsive and alignment issues
- Performance: slow loading, unnecessary re-renders, messy code
- Unfinished pages, components and features
TECH STACK
React, Next.js, TypeScript, Redux Toolkit, Zustand, TanStack Query, REST/GraphQL, Tailwind, Shadcn/Radix UI, Vite, ESLint
HOW IT WORKS
1. You send the repo and a description of the bug
2. I find the root cause not a quick hack
3. I fix it on a separate branch and deliver a clean pull request
4. You review it, revisions included
WHY ME
- 7+ years in fintech and product startups
- Clean, maintainable, production-ready code
- Average response time: 1 hour
Not sure which package fits? Send me your repo or a screenshot and I'll scope it for free within an hour.

Hi there! I’m a passionate Frontend Developer with over 7 years of commercial experience delivering high-performance web applications for both product-led startups and fast-paced outsourcing agency teams.

FAQ
Can you add a small new feature, not just fix bugs?
Yes. Components, pages, API integration, responsive layouts. Message me with the details and I'll send a custom offer.
I don't know how many bugs I have. Which package should I choose?
Send me your repository or a screenshot and I'll check it and recommend the exact package within an hour. Free, with no obligation.
What if you can't fix my bug?
You get a 100% refund. I only accept projects I'm confident I can solve, and I tell you honestly before we start.
Will you break my existing code?
No. I work on a separate branch and deliver a clean pull request, so you can review every single change before merging.
Do you work with legacy or messy code from other developers?
Yes. Most of my orders are exactly that — inherited projects, unfinished code and unclear documentation.
Do you sign an NDA?
Yes, I'm happy to sign an NDA before you share your code.
