Product designer
based in Stockholm.

I'm a product designer at Storytel with 4+ years of experience building digital products at scale. My focus is the detail that decides whether a product feels considered — the transitions, the feedback, the moments between states.

Alongside that work I run an ongoing practice in AI-driven product development: designing, prototyping and shipping products end to end, with AI embedded in the process rather than bolted on as a feature. Three of those products are in progress right now — Eden, Boddy and Trejda.

I write up what I learn as I go in my devlog — the decisions, the trade-offs, the experiments that didn't work, and what made it into the product.

I'm based in Stockholm, Sweden, where I live with my girlfriend and our dog Bonnie.
