I'm a software engineer who fell in love with Ruby. When I’m not travelling, I’m based in Slovakia working remotely as a full-stack developer for Skillandia and making side projects, such as LocaleData, DeliveryHunt or Writingy.

Over the years I worked for an IT university as a researcher, wrote some technical articles for DigitalOcean, managed several servers and created a lot of web sites and applications. I've been involved in many tech areas such as distributed systems, big data, artificial intelligence, knowledge discovery or computer vision.
