Worked on the navikt/pensjonsbrev repository to implement a new letter template for Uføretrygd, addressing income-based changes for the upcoming year. Developed detailed backend logic in Kotlin and Java to calculate and communicate updates related to Uføretrygd, child supplements, and survivor supplements. Updated API models and integrated a template engine to ensure accurate rendering and compliance with regulatory requirements. Adjusted test fixtures to validate the new template’s output, supporting end-to-end correctness. This work improved the clarity and reliability of user notices, reducing the risk of incorrect communication and enhancing the overall quality of information delivered to end-users.
