Polarion Software
ScrumMaster

As ScrumMaster for three 6-member teams at this rapidly growing international company, I oversee all daily production work in a fast-paced development environment. I keep in close contact with the entire team to make sure they are happy and have everything they need. This can sometimes involve insulating the team from interruptions coming from outside R&D, serving as "point man" and troubleshooter to keep the team focused on delivering software on time according to plan.

I also lead and moderate all ScrumTeam meetings, which involve remote stakeholders as well as the team. Removing any kind of roadblock to productivity is my daily routine. Since I joined the company, the R&D team has never missed a release target.

06/2009 - 1/2011

I was in charge of implementing Scrum on all development projects of Radio Impuls. I was ScrumMaster of one Scrum team (8-10 people), facilitating their work and helping them resolve any issues blocking or reducing their productivity.

03/2007 - 06/2009
Unicorn a.s.
Ruby (on Rails) & Javascript Developer

I developed submodules for the Unicorn Universe Information System using Ruby and JavaScript. I was responsible for delivery of complete solutions, including the test cases. Work involved task analysis and development of class and case diagrams. I was also responsible the entire submodule (script), from for the architecture and design through delivery and deployment.
