About

I am a full-stack developer passionate about building user-friendly systems with the user experience at the center. Based in Øygarden outside Bergen, Norway, I hold a Bachelor of Science in Informatics from NTNU in Trondheim. With experience in .NET, Angular, React, React Native, Python, Java, SQL, and Figma, I have been working at ACOS AS since 2019, focusing on converting Windows applications to multi-tenant, microservice architectures. Currently, I am employed at Frende Skadeforsikring, working primarily with .NET (F#) and React on their online insurance store.

Professional Experience

Full-stack Developer

Frende Skadeforsikring, Bergen

November 2025 – present

Working as a full-stack developer on Frende's digital insurance store, where customers can buy and manage insurance products online. The solution is part of Frende's customer-facing platform and includes both frontend user flows and backend services related to pricing, validation, product configuration and integrations.

My work is primarily with .NET, F#, React and TypeScript. I contribute to further development and maintenance of the storefront, including backend logic, domain validation, mapping of insurance products and coverages, and frontend functionality used in the purchase flow. The role requires working with complex insurance rules and translating business requirements into clear and reliable technical solutions.

I have also worked with automated testing, troubleshooting across environments, and investigation of issues in build and test pipelines. This includes identifying differences between test environments and contributing to more stable releases through clearer diagnostics and improved test coverage.

Full-stack Developer

ACOS AS, Straume

November 2019 – November 2025

Worked as a full-stack developer on the modernization of an existing Windows application into a web-based solution built on a multi-tenant microservice architecture. The project involved moving functionality from an older desktop application to a more scalable and maintainable platform using modern web technologies.

My work was mainly with .NET, Angular, AngularJS, TypeScript and SQL. I contributed across both frontend and backend, developing new functionality, maintaining existing features and adapting the solution to an architecture where multiple customers could use the same platform in a secure and structured way.

The role involved gradual modernization of legacy code, integration between new and existing services, and close collaboration with other developers to ensure that the solution could continue to evolve without losing important functionality from the original application.
