An engineer.
A spatial perspective.
I work where software meets the space around us.
I’m a Senior Unity/XR Software Engineer and Project Lead based in Kolding, Denmark. My work covers VR, mixed reality, interactive 360° media, and multi-user platforms for healthcare, education, and enterprise customers.
I take solutions from requirements and immersive UX through Unity/C# architecture, backend integration, customer validation, and production release. Before software, I worked in architecture and 3D visualization — a background that still shapes how I design spatial experiences.

Unity, XR and AI project work
VR training and simulation
I build interactive training with Unity and C#, from patient scenarios and simulated equipment to instructor interfaces and live feedback. Explore my medical simulation work in Copenhagen.
Shared worlds and interactive learning
My work includes multiplayer VR, synchronized avatars and voice, plus 360° video tools with branching, hotspots and quizzes. See TakeAWalk VR and Interactive 360° Learning.
AI characters and connected experiences
I integrate conversational AI, speech recognition, lip-sync and backend services into immersive applications. My projects include Danish-speaking avatars and an AI-guided vision simulator.
Can you make an interactive portfolio like this?
This portfolio brings together a cursor-following avatar, video showreels and an AI guide grounded in my professional experience. If you have a similar idea, tell me what you want to create.
Can I contact you about freelance or project work?
Yes—send me your idea, target platform and timeline. I’m based in Kolding, Denmark. We can discuss how my Unity, XR and AI experience fits, and I’ll confirm the scope, availability and working arrangement directly with you.
