Fredrik Jenssen is a pragmatic full-stack software developer with nine years of experience and an M.Sc. in Computer Science, currently building customer-facing insurance systems at Fremtind in Oslo. He has driven significant frontend modernizations—most recently migrating an AngularJS app to React—and pairs that with backend work like microservices, API integrations and automated end-to-end testing. Fredrik excels at turning domain complexity into intuitive UIs and reliable processes, having shipped simulation and calculation-driven features at Oliasoft and live-chat and CI migrations at Alv. A strong communicator and workshop facilitator, he also focuses on team play and developer ergonomics to accelerate delivery. Colleagues benefit from his mix of hands-on coding, systems thinking and a willingness to take ownership from prototype to production.
