How I work
Senior product engineering with real ownership and a security-minded approach across the stack.
Product ownership
Ship features and systems end to end: UI, APIs, data, billing, and the operational habits that keep them alive.
Pragmatic architecture
Boundaries that survive integrations, CMS constraints, and real traffic without over-engineering the obvious.
Technical leadership
Mentoring engineers, shaping frontend standards, facilitating technical discussions, and helping teams make practical architecture and delivery decisions.
Engineering quality and security
Tests, accessibility, auth, and common web risks treated as craft, so teams deliver without constant heroics.
