User:Krzysztof Ziemak

I am 62 years old and I am a graduate in mathematics from 1985 at the University of Warsaw (Bialystok branch, I was a student, prof. A.Rotkiewicz), however, I did not work as a mathematician because I have been an IT specialist for over 30 years, including almost 20 years working as ABAP/4 programmer in SAP R/3 systems (over 1 million lines of written code). I've been also programming in PARI / GP for a over year now and I'm playing mathematics using PARI/GP. I like to play chess. My mailing address: kziemak56@gmail.com
