Riajul Islam
Shopify & CRO developer Available for projects

I don't just write code.
I make it ship.

I build and optimize Shopify stores that load fast and actually convert — headless Hydrogen, custom themes, and the CRO work that turns the traffic you already have into orders. Got a store to build or fix? I make it ship.

— Conversion-first

Stores built to
convert, not just look good.

CRO sits at the heart of every Shopify build I ship — audits, A/B tests and checkout tuning that grow revenue from the traffic you already have. Same visitors, more orders.

Small PRs, clear commit messages and a preview deploy on every push, so you always see progress.

Real feedback on a real deploy. We refine, test and tighten until it's right, not just done.

Questions,
answered.

Are you open to full-time roles?

Git-based, async-friendly and documentation-first. Small PRs, preview deploys, clear standup notes — I slot into existing workflows quickly.

Yes, on a limited basis. Each project is scoped and quoted up front — share your timeline and budget on the contact form and I'll tell you honestly what's realistic.
