My Journey

As a passionate software developer focused on C# and the .NET ecosystem, I have made it my mission to develop high-quality and maintainable software. Since 2020, I have been supporting companies as a freelancer in implementing their digital projects.

Currently, I serve as Head of Development at Aizpun Consulting . My focus there is on .NET C# development in the areas of API and Blazor. This experience from daily work with enterprise systems flows directly into my freelance projects.

My Approach

Every project starts with a thorough understanding of the requirements. I value clean architecture, testable code and transparent communication. My goal is to deliver not just a working solution, but one that is maintainable and extensible in the long term.
