At university I studied applied mathematics, wrote lots of algorithms for calculus, combinatorics. For my final paper I had to get into heuristic algorithms, which are totally awesome!
After getting my degree I decided to switch into web development - it was very overwhelming at first, but the experience dealing with algorithms and logic in math helped out immensely.
Nowadays i usually work with PHP, Symfony, but I really like challenge myself by getting into JS world - mostly React, Redux and other latest hype trains :) I also work with front end CSS, SEO, web standards and whatever needs to done. They call me the idea generator.
