01 — About

About

I’m a software engineer from Sweden with a decade across telehealth, security, ad tech, e-commerce, fintech, and online gaming. Frontend at the core, increasingly fullstack, and lately shipping AI-driven product features. I care about type, motion and the small details that turn a screen into a place.

Along the way I’ve worked with a fintech company, an online casino platform, a security company, a skincare platform, and one of the world’s most visited websites.

These days I’m at GetHarley, working on AI features for clinical consultations like transcription and treatment-plan generation. I’m happiest when the boundary between design and engineering gets fuzzy.

You’ll find me on LinkedIn , or you can email me directly. Always happy to talk shop.
