About me

Hi. I work in software development - both as product manager and web developer. I appreciate delivering software that solves business problems. The process from discovering the core of a complex problem to developing technical solutions that work is simply great. It is about collaborating with motivated peers, leading vivid discussions, learning along the way, and the feeling of creating something useful that keeps me motivated day in, day out.
