About Hamza

Is your web app failing because of build errors, broken APIs, authentication problems, or deployment issues?
I help startups and businesses diagnose and fix production problems in Next.js, Node.js, and TypeScript applications — from Vercel deployment failures to backend and database issues.
Common problems I solve:
✅ Next.js build and deployment errors (Vercel, environment variables, CI/CD)
✅ API bugs, broken integrations, and webhooks (Stripe, PayPal, third-party APIs)
✅ Authentication issues (JWT, sessions, OAuth, RBAC)
✅ Backend errors, database connection problems, and performance issues
✅ Frontend bugs and full-stack debugging
My approach is simple: I don't just remove the error message — I trace the root cause, fix the underlying issue, and help prevent it from happening again.
I also build full-stack SaaS applications from scratch using Next.js, Node.js, TypeScript, Docker, and modern deployment workflows.
Send me your error message or describe what is broken. I’ll help you understand the issue and the best way to fix it.
