BIOGRAPHY

Full-stack engineer with 5+ years across travel-tech, developer platforms, and consumer browsers. I work across the stack — Java / Spring Boot microservices on the backend, React / Next.js on the front — and I'm comfortable owning a feature end-to-end on a single ticket.

Most recently: building Vietnam's Booking.com / Agoda equivalent on a 30+ engineer team. Before that: sole front-end owner of NAVER Corp's enterprise-wide license & vulnerability platform, deployed across every NAVER project globally.

Born in Ukraine, of Vietnamese origin. Quadrilingual.
