I build and scale high-converting Shopify storefronts. 6-figure revenue and counting.
Senior Software Engineer with 5+ years shipping production e-commerce systems. I own Shopify stores end-to-end — from theme architecture and Liquid customization to checkout flow, omnichannel integrations, and conversion optimization.
Currently Senior Shopify Operator at Scale Army (Charlotte, NC · Remote), leading complex Shopify operations, technical SEO, and data management for high-volume B2B and B2C environments. In parallel, I'm the technical partner and sole engineer for an international luxury fashion brand through Virtustant, where I've driven a 455% increase in platform sessions, 114% in orders, and 74% in total sales.
I founded and operated Martin, a men's fashion Shopify store that scaled to 6-figure revenue, ~2,000 orders, and 297,000+ sessions — engineered and operated end-to-end as a single founder.
