I will fix bugs and errors in your react nextjs nodejs or typescript app

Are you struggling with bugs, errors, or unexpected issues in your React.js, Next.js, or Node.js application? Maybe your frontend UI is broken, your Next.js app isnt building correctly, or your Node.js backend keeps throwing 500 errors.

Bugs waste time, frustrate users, and cost businesses real money. Thats where I come in. As a Senior Full Stack Developer with years of hands-on experience (and academic research rigor at the PhD level), I specialize in debugging, fixing, and optimizing full-stack applications.

My role is simple: find the root cause of your problem, fix it cleanly, and ensure your app runs smoothly and reliably.

What I Can Fix for You

I handle frontend, backend, and deployment bugs across modern full-stack stacks:

Frontend (React.js / Next.js)

• UI glitches (buttons, forms, navigation)
• Rendering & hydration errors in Next.js
• Routing issues, broken links, SEO mismatches
• React state management problems (Redux, React Query, Context API)
• TypeScript typing issues

Backend (Node.js / Express.js / APIs)

• Server crashes, 500 errors
• Database connection issues (MongoDB, PostgreSQL)
• Authentication & session handling bugs
• API routing errors (REST, GraphQL)
• Performance bottleneck
