Senior Unity developer for XR & games
9+ years building XR experiences, games, apps, and tools with Unity and C#
I’m Alexander, a Copenhagen-based Senior Unity Developer who loves building interactive stuff in 2D, 3D, and XR. I get a kick out of solving tricky problems, writing clean and fast C# code, and engineering systems that just work.
Beyond the code, I care about user experience, the details, and how people interact with what I build.
Whether you're making a game, an XR app, something cloud related, or just need a quick prototype, I'd love to help building it!

Some people I worked with
I highly recommend Alexander for Unity development work
I hired Alexander as a freelance Unity developer for two projects - three museum applications for Kongernes Jelling and a historical interactive installation for a large Danish toy company. I was consistently impressed by his technical expertise and professional approach.
Alexander writes clean, efficient code and maintains excellent project structure. His communication was outstanding throughout both engagements - he provided regular updates, asked good questions, and met deadlines. His structured development approach made managing these projects straightforward and successful.
I highly recommend Alexander for Unity development work. He’s a skilled programmer who delivers quality results and is very easy to work with.
Alexander is a very skilled Mixed Reality Developer
We collaborated closely on developing a visionary and easy-to-use MR application - Tutorio - for Microsoft HoloLens 2. While the application feels simple for the user the underlying implementation and technology stack implemented by Alexander is truly advanced. The application is built with Unity and MRTK3 and deeply integrated with Microsoft Azure, Azure Authentication, and Azure Spatial Anchors.
As a person and colleague Alexander is very proactive, able to work independently and always striving to find the right balance between perfection and getting things done.
I highly recommend Alexander as an MR/XR developer.
