My name is Lucas Mendelowski and I’m software engineer focused on building web applications from Krakow, Poland.

I mostly work with Ruby (on and off the Rails) and modern JavaScript frameworks (Ember.js / React).

This website is my knowledge base of all the things I learned across a variety of languages and technologies.
