Now in London, looking for what's next as a founder.

@singularityfm — where I write about all of it

about

I've spent 14 years building things at the intersection of engineering and product. Started as a software engineer at Yandex, ended up running their analytics products — Metrica, AppMetrica, and helped launch ClickHouse as open source. Somewhere along the way I ran mobile development for Yandex's main apps, then became CTO and CPO of their quick-commerce business.

From 2022 to 2026 I led AI at T-Bank — research, LLMs, computer vision, speech, recommendations, the whole stack. We built Gen-T, our family of large language models. The AI work my team did generated over $100M in annual business impact.

At heart I'm a tech enthusiast and an innovator — grounded and practical about what works today, but always thinking about what's next. I care about how AI changes the way we build products, how organizations scale, and what happens when the technology is actually good enough to matter. I talk about this stuff publicly and write about it on my channel.

Based in London, looking for my next big thing — as a founder or technical cofounder. If you're building something ambitious in AI, let's talk. Meanwhile: vibecoding my own self-developing agent harness system, thinking about agent-to-agent protocols, speaking about AI's second-order effects. Reading too many papers and not enough fiction.
