About this gig

Is your website broken, misaligned, or throwing JavaScript errors? 

I'll fix it fast and clean.


I specialize in diagnosing and fixing frontend issues across HTML, 

CSS, and JavaScript whether it's a layout that broke, a button 

that doesn't work, or a console full of errors.


WHAT I FIX:

  • HTML structure errors & validation issues
  • CSS layout bugs (flexbox, grid, alignment, spacing)
  • Responsive/mobile design breakage
  • JavaScript & jQuery errors
  • Cross-browser compatibility issues
  • Broken animations or transitions
  • Console errors & warnings
  • z-index, overflow, and positioning issues


️ TECH I WORK WITH:

HTML5 | CSS3 | JavaScript (ES6+) | jQuery | Bootstrap | 

Tailwind CSS | React (JSX/styling) | Vanilla JS


HOW IT WORKS:

  1. Share your website link or code files
  2. Describe what's broken
  3. I'll diagnose, fix, and return clean working code


Fast delivery | Clean code | Clear communication
