Hi, I’m Juraj Kostolanský,

a Ruby on Rails web developer.

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 web developer and system administrator 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.

If you need any help, or if you just want to get in touch and say hello, email me at juraj@kostolansky.sk or tweet at me at @jkostolansky.
