About
An infrastructure engineer who moved into retail-tech project management. I bring deep Linux experience to the practical work of getting systems shipped.
For more than a decade I built and ran the systems that keep businesses online — mail platforms for 90,000 customers, high-availability clusters, Ceph storage and infrastructure-as-code. Today at H&M I support global IT rollouts from the people side, preparing and running the works-council negotiations that get new systems approved and adapted to each local market. Lately I'm deep in the AI and LLM tooling reshaping how teams build.
