Greg has been programming since the 80s. He's lived and worked in the US, China and Poland. In 2005, whilst working in Beijng, his idea to automate the programmer recruitment process enabled a massive hiring campaign of his employer. The idea eventually evolved into Codility (full "Genesis"). Greg holds an MSc in Computer Science from the University of Warsaw. He won a bronze medal at the International Olympiad in Informatics, co-organized many programming contests, co-designed SystemVerilog Assertions, led the development of OpenC++ and translated several technical books into Polish, including Donald Knuth’s “The Art of Computer Programming”. Greg hacks at Warsaw Hackerspace and is a passionate pianist and organist.
