About

What I work on

I spend my time building open-source tools that empower individuals and merchants to accept Bitcoin without intermediaries. BTCPay Server is used by thousands of merchants worldwide and is entirely community-funded.

Your support helps me continue working full-time on freedom tech — no corporate sponsors, no strings attached.
