About this gig

Hi, I'm Muhammad Hassaan, a web developer who specializes in bug fixing and code debugging for websites and web applications.


If your site or app has errors, broken functionality, or unexpected bugs, I can help find the issue and fix it with clean, working code. My core debugging skills include:


  • JavaScript bug fixing
  • React.js bug fixing (component errors, state issues, rendering bugs)
  • Node.js & Express.js backend debugging
  • HTML & CSS layout and styling fixes
  • Python script debugging

I approach every bug fix by first understanding your codebase, reproducing the issue, then applying a proper fix not just a quick patch that might break something else. Whether it's a frontend bug fix, backend bug fix, or general website error fix, I test thoroughly before delivery.


I'm upfront about scope: some issues turn out to be deeper architectural problems that need more investigation than a small fix. If that happens, I'll tell you before doing any extra work never silently, never with surprise charges.


If you're dealing with a JavaScript error or a website that's not working right, message me your issue first happy to take a look before you order.
