About me
When I’m not travelling, I’m based in Slovakia working remotely (mostly) as a Ruby on Rails web developer, or making side projects, such as LocaleData.
Over the years I worked for an IT university as a researcher, wrote some technical articles for DigitalOcean, created an enterprise learning platform, worked on machine learning and computer vision tasks in the fashion industry, managed several servers, and created multiple web sites and applications.
Do you want to hire me? Need any help? Or just want to get in touch and say hello? I love hearing from people, so please email me at [email protected].
