About this gig

Having issues with your Node.js app? I specialize in debugging existing systems, finding root causes, and fixing problems properly, not quick hacks.

I've worked on live production systems where stability matters, and I'm comfortable jumping into unfamiliar codebases.

I can help with:

  • Runtime errors and crashes
  • API issues
  • Async / promise-related bugs
  • Database and query problems
  • Environment and deployment issues

Clear communication and honest feedback guaranteed.

  • Programming language

    • JavaScript

  • Expertise

    • Algorithms & Data structures
    • Debugging
    • Performance
    • Databases

  • Backend framework

    • Express.js
    • Node.js
    • Other
