I build products that move money.

Product leader in payments and fintech. Physicist by training. I also build communities and tools, mostly for people who spend their weekends outdoors.

For the last decade I've built B2B platforms in crypto and fiat payments, retail pricing, telecom data and consumer lending. Most recently I was Chief Product Officer at INXY Payments, where I owned on/off-ramp, exchange and mass-payout products for EU clients under MiCA.

Before product, I did a PhD in physics at Moscow State University and a Marie Curie fellowship in Eindhoven. Outside work I founded Triathlon Sale, a community of 15,000 triathletes that I ran for nine years. I also built Monopatia, a guide to every hiking trail in Cyprus. Most weekends I'm racing, or climbing hills on a bike.
