Senior-Level Bug Fixing Node.js | NestJS | React | Next.js | React Native


Is your app broken in production? Getting cryptic errors you can't trace? 

I fix bugs fast with a root cause explanation so the same issue never 

comes back.


 ISSUES I FIX:

  • Node.js / NestJS API errors, crashes, memory leaks
  • React / Next.js rendering bugs, hydration errors, build failures
  • React Native crashes, navigation issues, native module errors
  • Authentication & JWT issues (Passport, NextAuth, custom)
  • Database errors (MongoDB, PostgreSQL, TypeORM, Mongoose)
  • Deployment failures (Docker, PM2, Nginx, VPS, AWS, Railway)
  • Performance issues slow queries, N+1 problems, memory leaks
  • CORS, environment variable, and config issues
  • Third-party API integration bugs (Stripe, OpenAI, Firebase, etc.)


WHY HIRE ME OVER OTHERS:

I don't just patch symptoms I fix root causes. Every fix comes with 

an explanation of what went wrong and how to prevent it.
