Frontend Developer

Krzysztof Kisielewski

When I was young, I wanted to be a developer, but my plans had to change when I met my wife. So I started my work career as a salesman. To be honest, I was pretty good at this, but it wasn't something that I liked. After some time, I decided to change it and come back to the previous idea for myself. I started learning to code systematically every day! And it was worth it! Because I got to Codetain as a frontend developer. In my spare time I play games and build Lego with my son. I also try to keep in shape, so I train regularly with my boys.
