Profile

I've been working with Software Design most of my career and always try to find new exciting Software projects on my free time. My software experience is broad working with many languages and tools to solve complex situations in either the robust and performance critical embedded environments at work or developing creative and fun apps at home. I work with a test intense attitude and like to refactor and make clear code. Version control and automated test regression is natural for me.

My later years have led me to do more systemization. As a senior, I have been a team leader and scrum master showing the way forward both regarding software design/architecture but also introducing many new tools (version control, review, testing, automation, storage, scripting etc).

Finally I have been fortunate enough to be entrusted for acting Line Manager several times with recruting, personnel development, delegation, studies, reporting and prioritizations on the agenda adding up to almost a year in experience.
