SKILLS
I am used to work on large projects and in an agile development environment. My main experience is on Java backend and full stack iOS development. With twenty years experience in Java development and ten years in iOS development. I have a solid knowledge in Java EE and in the last two years I have primarily used Java micro services with Spring Boot.

My favourite project is a highly distributed backend system with messaging and RESTful interfaces. A bonus would be to be able to use my mobile development experience as well.

Since 2006 I have worked with agile methodologies, primarily with Scrum. I took a Scrum Master certification and have Scrum Master experience from various projects since 2008. I do prefer to be part of the development and as such I like the mixed developer / Scrum Master role.

Regarding technology and implementation, I was considered the “go-to-guy” from my team members in recent years. I am always open for questions and suggestions. I believe in team work and shared responsibility and if I spot communication or other issues within the team, then I will try to resolve those problems.

I work best in teams applying clean code principles with continuous integration and delivery. When a team is not experiences in this, then I will work on sharing my knowledge and lead by example.
