About
I build Shopify stores that teams can keep changing.
I’m a systems engineer and Shopify developer with more than nine years in ecommerce. I spent the last six building high-conversion stores for international DTC brands at Trafilea Group, and before that led Magento to Shopify migrations at Redstage.
Today I work across the whole Shopify surface: Online Store 2.0 themes, embedded apps, checkout extensions and Shopify Functions, and Hydrogen storefronts. I care about the parts merchants feel: speed, a theme editor that makes sense, and features that keep working after the next app install.
I write a short spec before I write code, ship through reviewed pull requests, and use Claude Code and Codex every day to move faster without lowering the bar.
