About

A senior engineer focused on systems that stay clear under growth.

I build, modernize, and stabilize production web platforms across commerce, publishing, SaaS, internal tools, and content-heavy systems.

I work across frontend architecture, platform foundations, content modeling, and delivery systems. The throughline is clarity: make the system easier to extend, easier to reason about, and less expensive to change under pressure.

Most of my work sits where delivery slows down: route structures that drift, content systems that stop fitting the product, release paths that feel unsafe, or shared abstractions that are now hiding more than they help.
