Summary

In recent years, as you can see from my profile, I have primarily worked with Microsoft products and technologies, which I have studied in depth.

For a long time, I worked as a consultant for a large financial services provider in Essen, among other places. I was responsible for data migrations, portfolio transfers and the further development of in-house applications.

As the existing application was gradually being migrated to C#/.NET, I developed a complex accounting module in C#.NET. Since this was an international team, I have experience with offshore projects (especially with Lithuania).

My responsibilities in the team included preparing functional specifications and leading a sub-project.

After completing my thesis at Bayer AG, I worked in medical documentation for about 1.5 years, giving me in-depth knowledge of medical and chemical research.

I am highly willing to learn new development tools or take on other tasks, and I welcome these opportunities.
