About this gig

Is your website slow, glitchy, or breaking on mobile? Let's 

fix that fast.


I'm Shivesh, a full-stack web developer who builds and 

maintains websites professionally. I regularly handle bug 

fixes, speed optimization, and mobile responsiveness issues 

across my own client projects including image compression 

techniques that reduced load times significantly on a 

recent eCommerce platform.


What I can fix:

CSS/layout issues (broken alignment, spacing, overlap)

JavaScript bugs (broken buttons, forms, functionality)

Slow loading speed (image optimization, code cleanup)

Mobile responsiveness issues

Cross-browser compatibility issues

Minor content/structure updates


Works with: HTML/CSS/JS sites, Shopify stores, and most 

custom-built websites.


I respond quickly, diagnose the actual root cause (not just 

a quick patch), and fix it properly. Send me your website 

URL and a description of the issue I'll confirm scope 

before starting.
