Frontend is what I like doing most: HTML, CSS, TypeScript and how things feel to use. I've led frontends for IKEA, Bombardier/Alstom and HMS. This year I've built three products of my own with Claude Code, from the interface down to the database, and all three are in production.

In short

Available: Now. Hybrid 2–3 days a week in Gothenburg, or remote from anywhere in the world.
Frontend: Lead frontend in Vue for IKEA and Bombardier/Alstom. This year React and Next.js in three products of my own.
Backend: TypeScript and SQL today: Postgres with row-level security, webhooks with retries, and APIs. Java 2000–2012.
AI: Claude Code writes much of the code, and I read every change. In the products, language models read and explain, but they never decide on their own.
Leadership: Group Lead and consultant manager at Devoteam, while I kept coding.

How I work with AI

I use Claude Code with rules and skills per project. Work starts from issues, decisions are written down as ADRs, and logic that has to be right gets tests first. I read every change before it ships.
