About my work

I build end to end.

I work on product requirements, interface design, frontend, backend, and deployment. After launch, I handle support, bug fixes, and ongoing improvements.

Most of my work is in ecommerce: Shopify apps, product search, and analytics for app developers. The case studies explain the user problem, implementation, and technical trade-offs.
