Since 2006, I have worked as a programmer and team leader in the IT industry. I have used many different technologies and programming languages in my practical work to develop distributed systems. For the past few years, I have been doing less programming and databases and more analysis, design, and architecture of IT systems and team leadership. I am currently rusting my Java programming skills while serving as a team captain at Dynatrace.
