I'm a full-stack software engineer living in Stockholm, Sweden, with 6+ years of experience building web and mobile products in TypeScript. I like to own a problem end to end, from the database schema and the NestJS API to the React interface someone actually uses, and I care about code that is clear, well structured and easy for the next person to pick up.

I'm drawn to software that does something useful beyond the code. I've built tools to cut food waste, make the carbon footprint of software features visible, and protect people's personal data when contracts meet AI. Along the way I've shipped a nursing exam-prep platform, a peer-to-peer exchange, a marketplace app on Google Play and an npm SDK.

I learn by building and by being tested. I'm learning Go with AI tutors that quiz me before I move on, and exploring machine learning. This profile collects my featured projects, the tools I use and what I'm learning next. I'm open to collaborations, open-source work and new opportunities, so feel free to get in touch.
