I've been working in IT projects for healthcare, energy and oil&gas industry and also oil and gas industry for over 12 years. I've been implementing Scrum for over than 6 years in our local development team for healthcare solution covering different projects on implementation phase. During the first 4 years i've been acting as a product owner for this solution, gathering all requisits and priorities from 3 projects and then building into a single product backlog.
For over 2 years now i've been acting as product owner for a project consisting building a solution for oil&gas industry. For that period i've also been coaching the local scrum master for the healthcare projects, and in some points in time also acting as scrum master
