About this gig

Struggling with a stubborn bug? Lets get your code back on track.


Errors in Next.js, React, or JavaScript can stall your project for days. Whether its a hydration mismatch, a broken state loop, or a deployment failure, I provide clean, efficient, and professional fixes. I specialize in the modern App Router as well as classic Pages Router and React Hook architectures.


️ What I Can Fix for You:


  • Next.js: Hydration errors, Server Actions, Middleware, and Vercel build failures.
  • React JS: State management (Redux/Zustand), useEffect loops, and Custom Hooks.
  • JavaScript: Async/Await issues, API integration, and ES6+ logic bugs.
  • Performance: Optimizing LCP/CLS and fixing memory leaks.
  • UI/UX: Responsive design fixes and Tailwind CSS/Material UI glitches.


Why Choose Me?


  • Clean Code: I follow industry best practices and TypeScript standards.
  • Root Cause Analysis: I explain why it happened so you can avoid it later.
  • Fast Delivery: Most bugs are resolved within 24 hours.


NOTE: Please message me with a description of the bug before ordering to ensure the fastest delivery!
