Backend Developer

Mikołaj Kalwa

I’ve been coding since high-school and happily, now it’s a part of my professional life, as well. Gaming is my other main hobby — especially playing League of Legends with my friends. I’m also passionate about LoL as esports so on the weekends you can find me watching LEC (LoL European Championship). Besides, I develop my own projects. One of them is a bot on Discord that informs me about current games on -100% sale. To my surprise, there are more and more people using my bot. It was supposed to be a small project mainly for my use, but it’s exciting to see other people make use of my work.
