About

Passionate programmer and product developer serving since 2002 who likes programming, fintech, cryptocurrencies and strategic sectors.

Successfully executed freelance, open source, startup and enterprise projects. With cross-functional and cross-cultural teams, I've had the opportunity to work with fascinating projects and people.

I build scalable micro services, real-time apps and mobile apps using innovative technologies in Node and the JS ecosystem including React and React Native.

Pure backend technologies I've experienced include Elixir, Rust, Python, Scala and good ol' PHP back in the day.
