Summary

I have been working professionally and with passion in computer science since 2009. Between my bachelor's and master's studies, I worked as a full-time, hands-on software developer in various permanent positions. During my master's studies, I carried out small software projects on a freelance basis and am now working full-time as a freelance software architect, supported by my small development team.

My experience is primarily in .NET development of desktop, web, and distributed applications with C#. I am involved in planning, development, quality assurance, and software delivery. I focus on the system user and their needs and wishes, while keeping a clean architecture, a clear codebase, and high test automation to ensure quality.
