About
I build products, end to end
I'm Siarhei Hamanovich, a senior engineering manager. I lead engineering teams by day and still design, build, and ship web applications, AI tools, and Telegram bots - most of them carrying the same suffix that's become my signature: NEXT.
The teams pay the bills; the products keep me honest. Building one sharpens how I lead the other.
Leading at scale
Beyond my own products, I lead engineering teams of up to 130+ across Poland - owning hiring, talent development, and delivery. As EPAM's Global Assessment Head for JavaScript and Node.js, I set and run the technical bar for the discipline.
