ABOUT

Sandeep Kumar Singh

Freelance Shopify developer & web performance specialist, based in Surat, Gujarat, India.

I've spent the last 7+ years focused on the frontend and performance side of web development — Liquid templating, Shopify theme customization, and the kind of Core Web Vitals debugging that requires actually reading a waterfall chart, not just installing a caching plugin.

I work directly with store owners and businesses as a freelancer (Top Rated Plus on Upwork), and I measure my work by a simple standard: does the fix hold up, and did it move a real metric — PageSpeed score, conversion rate, or a bug that's actually gone.

HOW I WORK

A few things clients can expect

Direct communication

You hear from me — not a rotating team of unfamiliar names.

Built for international clients

Most of my clients are in the US, UK, and Australia. I overlap with EST/PST/GMT hours and keep updates async (Loom, written notes) so time zones don't slow a project down.

Root-cause fixes

I explain what actually broke and why, in plain terms, before proposing a fix.

Respect for existing work

I work inside live themes and codebases carefully, without breaking what already works.
