David worked on backend and DevOps improvements for the navikt/helse-spleis and navikt/helse-spesialist repositories, focusing on deployment efficiency and data model clarity. He tuned deployment triggers in navikt/helse-spleis, adjusting thresholds in YAML configuration to enable earlier, safer releases without altering application logic. In March, David enhanced CI/CD workflows using GitHub Actions and Kotlin, ensuring builds responded to changes in core modules for faster feedback. He also refactored domain models in navikt/helse-spesialist, removing unused fields to simplify maintenance. His work demonstrated a methodical approach to CI/CD, domain modeling, and refactoring, with clear traceability and low operational risk.
