};I build the software and systems that make e-commerce brands run and grow. I founded and scaled my own Shopify store to $120,000+ in gross sales, engineering the entire technical stack from scratch β storefront, custom apps, integrations, and marketing automation.
Today I'm focused 100% on Shopify & Shopify Plus: custom app development, storefront engineering, and the digital operations that power B2C and B2B commerce. I've owned production systems end-to-end as sole engineer and technical decision-maker for US and international teams, fully remote.
