Sondre Gundersen is a DevOps Engineer based in Oslo with nine years of experience combining backend development, test automation, and infrastructure work across startups and enterprise environments. He recently moved into a DevOps role at Favrit after four years as a software developer at Otovo, bringing practical production experience and a strong focus on reliability. An active open-source contributor, Sondre has improved test quality and fixed nuanced bugs in notable Python projects like Litestar and Polyfactory, often tackling edge cases such as decimal handling and ORMAR integrations. His background in finance (MSc) and business administration gives him a pragmatic, metrics-minded approach to engineering tradeoffs and automation. Colleagues value his attention to testing and maintainability—he routinely replaces broad fixes with targeted type-hinting and linting improvements that reduce technical debt. Outside work he’s the kind of engineer who surfaces obscure bugs in libraries, turning small fixes into bigger stability wins for downstream users.
