Tomas Larsen
Senior software developer · technical lead · product owner
Senior software developer, technical lead and product owner with 20+ years of experience — from independent web development since 2001 to PCI-regulated payment systems and modern AI tooling. I work best close to the business, as one experienced partner rather than a large vendor.
