Jonas Liahagen delivered a targeted documentation update for the replacement quay mitigation API in the RuterNo/adt-doc repository, focusing on clarifying the workflow and introducing new parameters to the API specification. He applied his skills in API design, technical writing, and documentation using JSON and Markdown to align the API documentation with current mitigation workflows. This work improved developer onboarding and reduced support queries by making integration expectations clearer and the API surface more discoverable. While the scope was limited to a single feature over one month, the update strengthened API governance and enabled faster, more reliable integration for downstream developers.
