Hey, my name is Jan and I’m a Ruby/Javascript developer based in Poland. Currently I’m working remotely for Leadfeeder.
I’m a programming enthusiast, mostly comfortable with the word „fullstack” – I’m simply there, where I’m needed at the moment 🙂
After hours I’m doing a bunch of generic hobbies – CrossFit, long distance running and electric guitar.
