Services
Four things I do — and do well.
Specialization beats generalization. I focus on the parts of Shopify that move revenue: how fast your store loads, how well it ranks, and how cleanly your theme and apps are built.

How I work
Senior engineering, without the agency runaround.
Most Shopify projects fail at scoping, not execution. I keep the loop tight: clear discovery, honest estimates, and weekly progress you can verify.
- 01
Audit & discover
We start with a free call. I look at your store, your stack, and your goals — then send you a one-pager with what I'd actually fix first.
- 02
Scope & plan
You get a fixed-scope proposal: exact deliverables, timeline, and price. No hourly meters, no surprise invoices.
- 03
Build & measure
I ship in small, reviewable steps. Every release is measured against the metric we agreed on — Lighthouse score, conversion, ranking, whatever applies.
