Ruby on Rails and Scrum Freelancer
During the past several years I have worked on many different projects, either as Ruby on Rails developer, Scrum consultant or Agile coach. My goal is to deliver tangible results and productivity in every project I take on. Please review the projects page to get a feel for the diversity I am able to handle. I am happy to provide more details about any of these projects.
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.
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.
