Experience Designer & Maker · Denmark
I’m Raj, a designer working across services, digital products, and technology. For 15+ years, I’ve moved between the big picture and the hands-on details — shaping experiences, making prototypes, and turning ideas into things people can use.
Away from the screen, I 3D print, solder ESP32 boards, and write code to test ideas in the real world.
2026 projects
Some are on the wall. Some are on my desk. Some are still on the build plate.

How I work
Find a real problem. Research it, prototype it and put it in people's hands. Watch what happens, then do it again.
Find a real one. Out in the world, not in a meeting room.
Talk to people. Watch what they actually do.
Build the cheapest version that could possibly work.
Give it away. Stop explaining it.
Watch. Write down what broke and what surprised me.
Change one thing. Then go round again.
One AI, maker or weekend topic every week for a year. Built, tested and written up.
15+ years of untangling big systems. Banks, healthcare, software and an AR/VR agency I co-founded.
I make things. I break things. I figure things out. Why I’d rather build an idea than talk about it.
I wrote a novel too. Awakening: Book One – The Forgotten Path Saga.
