About Jonas Andersson

Live in Borås, Sweden with my partner and two kids. I am most often described as calm and educational. The thing I enjoy most about coding is that awesome feeling when you solve a problem. In my free time I like to move. I run, swim, work out and climb. But I also like my quiet time with a good book, movie or studies.
