Jun 1, 2026June 2026 monthly performance summary for island.is is focused on delivering a targeted Job Listings enhancement that increases relevance, accuracy, and scalability of vacancy data. Key work delivered includes sorting job listings by publish date, integrating the new API to supply job categories, and updating filtering to utilize the new jobCategory field. These changes were implemented against the island-is/island.is repository with careful dataflow alignment between API, backend, and UI, enabling faster value realization for job seekers and recruiting teams. Impact highlights include improved listing relevance, a more accurate categorization workflow, and a foundation for scalable category data as job postings evolve. The work also demonstrates solid collaboration with automation-assisted fixes to ensure data consistency across external sources (e.g., elfur) and API-driven category data.

May 1, 2026Month: 2026-05 focused on stabilizing core pension workflow and enriching vacancy data with salary information from the Elfur API. Delivered two key changes in island.is: - Pension Application: Fixed forward navigation bug where empty employer entries blocked submission. The fix filters out non-empty employer entries prior to submission, preventing blockers when navigating back from the employers screen. Commit c13305262417dfc4873eabadc684f3dc6cb8a8d8. - Vacancy Management: Integrated salary terms from Elfur API into vacancy data structure to improve salary visibility and management. Commit 63a5a9ff89e4f1077fc27e79caa08083189fa0d0. Impact and outcomes: - Improved user flow in the Pension Application, reducing submission blockers and potential user frustration. - Enhanced vacancy management with salary visibility, enabling faster, better-informed hiring decisions. Technologies/skills demonstrated: - Front-end bug fixing and navigation flow improvements. - API integration and data parsing for external salary terms. - Data structure augmentation to support richer vacancy information. - Code collaboration and commit hygiene.

Mar 1, 2026March 2026 — Island.is: Implemented IP-based feature flag control for the Vacancies API, enabling per-client IP routing to determine which vacancies API to call. Added tests validating IP-based evaluation and correct API invocation based on flag state. Fixed and stabilized the feature flag IP lifting, addressing issues observed in related PRs. This work enhances rollout safety, reduces misrouting, and improves client-specific experiences across environments. Commits include b85e65bba6018c2eee7483e96748e8acafa8a987 and ac314004e543592a2b67dc4c34bd752028fa14df.

Feb 1, 2026February 2026: Delivered a key eligibility enhancement in island.is that guides users reapplying after a six-month gap in the basic certificate. Implemented a new eligibility reason BASE_CERT_OLDER_THAN_6MONTHS within the TM payment application, added user-facing messages, and updated the eligibility logic to clearly communicate requirements for reapplication after a payment break. This work aligns with policy, improves user experience, and reduces potential support friction.
