About

Full-stack developer building web and mobile apps, from database to user interface. I work AI-first, running parallel tasks with GitHub Copilot and Claude Code, and I'm at home on the infrastructure side with Docker, networking and server setup. Self-driven, quick to learn and focused on solutions that make my clients' work simpler.

Work experience

1. Full-Stack Developer

   Sep 2022 – Oct 2024 · 2 yrs 2 mos

   Uppsala kommun

   At Uppsala Municipality I worked in both the web team and the newly formed E-team, building and maintaining the municipality's digital services with React, .NET 8 and Optimizely 12. In the web team I maintained and developed key applications such as Hitta & Jämför, Uppsala.se, Brandförsvaret and Klimatprotokollet, built with an MVC architecture, Optimizely 12 and Razor and with a strong focus on accessibility. In the E-team I played a key role in building user-friendly services such as Senior Card and Civil Marriage, and both teams worked together on the app for Culture Night 2024. When the E-team was dissolved, I returned to the web team. I also shared responsibility for the web team's Azure DevOps environments, including CI/CD pipelines, and worked in Scrum.
