About
I lead product delivery and build software across web, mobile, and desktop. Over a decade across telecom and audio streaming (Zvuk, MTS, Nokia), I specialize in turning complex technical requirements into reliable production systems. At March Studio, I operate hands-on—designing interfaces, writing code, and driving agentic development workflows to ship products rapidly from idea to production.
