About this gig

Is your React, Next.js, or Node.js app throwing errors or behaving unexpectedly?


I'm Shahzad, a full-stack developer with 4+ years of experience building and maintaining production web applications. I can quickly identify and fix bugs in your existing codebase whether it's a broken feature, a console error, a layout issue, or something crashing in production.


What I can fix:

UI/layout bugs and broken responsive design

Broken API calls or backend errors

Authentication/login issues

State management bugs (React/Redux)

Database connection or query errors

Performance issues and slow load times


How it works:

  1. Share your repo (GitHub/GitLab) or code files, plus a description of the bug(s)
  2. I diagnose the issue and give you a quick estimate of scope
  3. I fix it, test it, and explain what caused it


Message me with details of your bug before ordering so I can confirm the right package for your project.
