The HUD shows full health and ammo, with a minimap displaying enemy positions. A radio icon in the bottom left indicates the player is carrying an in-game music device.

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.
