I specialize in React, Next.js, and TypeScript, with deep production experience in Shopify built on top of that foundation. Most of what I do comes down to one habit: I don't consider something finished when it works, I consider it finished when it holds up.

That means clean, maintainable code, performance that doesn't fall apart under real traffic, and interfaces that still feel right six months after launch. Whether it's a custom Shopify store, a landing page, or a full React application, that standard doesn't change.

Client Reviews

Trusted by teams who shipped with me.

A few words from founders, product leads, and fellow developers I’ve worked with on Shopify builds, React apps, and everything in between.

From a recent project

I'll be honest we'd already been through two developers before Haseeb, and both left the theme in a worse state than they found it. He spent the first call just asking questions: how we merchandise, why our return rate was high, things most devs don't bother with. The rebuild took five weeks instead of the three we'd asked for, but he flagged that on week two instead of letting the deadline slip quietly. Homepage went from 3.4s to 1.2s load time. Checkout abandonment dropped almost 20% the month after launch. I still message him with random questions and he replies within a day once on a Sunday.

We needed our dashboard rebuilt in Next.js three weeks before a board demo. He had a working version in ten days, then spent the rest of the time on things we hadn't thought to ask for loading states, permission edge cases, the boring stuff that actually matters.

Genuinely good with Liquid, which is rarer than it should be. He restructured our metafields so the merchandising team stopped filing tickets for basic product page changes. Only note the handoff docs were a little thin at first, but he fixed that within a day of me flagging it.

We inherited a half-built React app from another contractor no docs, a memory leak nobody could trace. He found it on day two, a socket connection that never closed, then quietly refactored the state layer without breaking anything downstream. That's the part that impressed me. Not that he fixed it, but that he didn't touch anything else while doing it.

React codebase rescue, agency handoff · Jan 2026

Marcus Oyelaran

CTO, Basecamp Studio

via Email

I send Figma files to a lot of developers and watch the spacing get rounded to the nearest 8px whether I intended it that way or not. He asked me about easing curves before I had even brought up motion. It’s a small detail, but it immediately told me he was actually reading and understanding the file, not just looking at the layout and translating it into code.
