Senior Ecommerce Engineer

I help businesses build, migrate, and grow their ecommerce sites with attention to SEO, analytics, integrations, and launch timelines. My work spans Shopify, BigCommerce, WordPress, Next.js, APIs, conversion tracking, and AI-assisted automation. I’m strongest when the project is technically messy, business-critical, and needs to be shipped correctly.
