Lars Hartvigsen contributed to the navikt/sokos-utbetalingsportalen repository by delivering targeted frontend enhancements and infrastructure improvements over five months. He migrated the routing system to React Router v7, introducing a mock sub-router for incremental adoption and improved maintainability. Lars implemented an App Switcher in the navigation bar with event tracking, and addressed navigation stability by handling browser popstate events to prevent route freezing. He integrated Umami analytics using environment-based configuration for secure, production-only tracking, and optimized header image assets by switching from PNG to WebP. His work demonstrated proficiency in React, TypeScript, and asset optimization, with a focus on maintainable solutions.

February 2025 — Navigation stability improvement for sokos-utbetalingsportalen. Implemented a back/forward navigation workaround for React Router by forcing a full page reload on popstate events to prevent freezing, using a popstate listener to replace the current location. This fix reduces navigation errors and preserves user session continuity during history navigation.
