Heidi Lammi-Mihaljov contributed to the Opetushallitus/kouta-backend repository by building and refining backend features that improved data management and API clarity. She implemented multilingual classification term storage and unified taxonomy with keyword management, enabling more robust search and discoverability. Heidi refactored the data model for classification terms, simplifying schema complexity and improving reliability, while also making modifier names optional to handle real-world data cases. She centralized display name generation logic using Scala utility classes, removed obsolete API endpoints, and enhanced CI/CD deployment governance with GitHub Actions. Her work demonstrated strong skills in Scala, API design, and database management.
