👨🏼‍💻 About

I’ve been in love with making things for the web since the early 2000s.

Over the years, I’ve worked with many different technologies and on all sorts of projects — from distributed systems to real-time single-page apps and polished responsive websites. I have a deep understanding of system architecture, backend and frontend development, UX, and related fields.

🚀 Work

These days I mainly build web apps with Python and JavaScript and work remotely with startups and companies from everywhere in the world.
