About this gig
Is your React app crashing? Next.js build failing? Having API integration issues or slow rendering? Let's find the root cause and fix it properly.
I provide professional debugging and performance optimization for React and Next.js applications, delivering clean, maintainable fixes rather than temporary patches.
I am a Front-End Developer with 3.5+ years of experience building B2B SaaS, dashboards, marketplaces, and data-driven web applications.
WHAT I CAN HELP YOU FIX:
- React/Next.js production errors, crashes, and build failures
- State management bugs (Redux Toolkit, Zustand, Context API)
- API integration and async data fetching issues
- Performance bottlenecks and slow UI rendering
- Hydration, routing, and component rendering issues
- Responsive layout and Tailwind CSS bugs
WHY WORK WITH ME:
- Root-cause debugging instead of unstable patches
- Clean fixes that respect your existing codebase
- Experience with complex SaaS and dashboards
- Clear communication about the issue and scope
Please message me before ordering with your error logs and tech stack context. I will review it and recommend the right package.

FAQ
What do you need from me to start debugging?
Please provide a clear description of the bug, steps to reproduce it, and relevant console errors or logs. Access to the repository or relevant code context is highly recommended so I can analyze the root cause efficiently.
Do you handle database, server setup, or backend bugs?
This gig focuses on React and Next.js frontend debugging. I can help with client-side API integration and data fetching issues, while database infrastructure and server-side backend logic are outside the scope of this gig.
What if the bug turns out to be more complex than expected?
I will first investigate the issue and clearly explain the root cause and required scope. If additional work is needed beyond the original order, I will discuss the options with you before proceeding.
