Is your Node.js application crashing, throwing errors, or behaving unexpectedly? I'm here to help.

I'm a backend developer specialized in Node.js and JavaScript, and I fix bugs quickly without breaking your existing code. Whether it's a small error or a complex issue, I'll find the root cause and deliver a clean, tested solution.

  • Async/await and Promise errors
  • Performance bottlenecks and slow APIs
  • Deployment errors (Heroku, Vercel, AWS, Render)
