About
I'm a full-stack engineer who likes the seams — where the database meets the UI, where a designer's intent meets the browser, and where a 5-person squad needs to ship something on Friday. Six years in, I've led teams across eCommerce, real estate, recruitment, and AI; the work I'm proudest of tends to look obvious in retrospect.
At Customily I'm on the integrations team, currently building the Customily ↔ Amazon Store integration. Before that I led the Partner Center squad at Buymed. Off-hours I freelance on SaaS platforms (Aspirez, Guglu CA), write occasionally, and try to keep a weekend habit of building one tiny thing from scratch.
