Portfolio
FORSBERG+two
Legendary Shopify app development studio from Copenhagen. I was helping Bjorn with building new app and developing AppKit - the framework for Shopify apps with Ruby on Rails and Hotwire.
Cook Smarts
Lifesaving meal planning service from California. I revived their old Ruby on Rails monolith, made a full redesign and implemented a huge list of long waited features. A lot of work and a lot of happy customers!
Busfor
The largest bus ticket selling platform in Eastern Europe acquired by BlaBlaCar. As a team leader and later CTO I participated in Ruby on Rails monolith development and built a mobile app with React-Native.
