PROFILE
Ilari Tommiska
Ilari Tommiska contributed to Opetushallitus/koto-rekisteri by building robust data import, validation, and management features, including scheduled imports and versioning for assessor data. He overhauled the language test UI using mustache templating and improved navigation for maintainability. Ilari established an end-to-end testing framework with Playwright and Page Object Model, enhancing test reliability and CI/CD readiness. He standardized OID handling across APIs and the database using custom JDBC converters and domain types, reducing data inconsistencies. His work also included integrating S3-backed storage for a question bank and stabilizing development environments, leveraging Kotlin, SQL, and Spring Boot throughout the project.

Jan 1, 2025Month: 2025-01 — This period focused on strengthening OID handling, data integrity, and API validation in Opetushallitus/koto-rekisteri. Delivered an OID type abstraction and domain-type enforcement to ensure consistent OID formats across the database, together with improved string-to-OID conversion via custom JDBC converters. Also aligned school OID processing with database types and external API validation by using organisaatio_oid for school_oid, handling empty values, and validating Koealusta OIDs through a dedicated Oid type and mapping service. These changes reduce data inconsistencies, mitigate ingestion risks, and enable reliable reporting and downstream integrations.

Nov 1, 2024November 2024 — Delivered two major feature areas in Opetushallitus/koto-rekisteri: (1) Arvioija data import, validation, and management with scheduled imports, versioning, conflict-safe persistence, and enum-based validation across YKI assessor data; and (2) KOTO language test UI overhaul with new templates, improved navigation, and mustache templating for consistent base templates. Fixed key issues: enhanced duplicate handling, validated stored tutkintotasot, clearer errors for empty-body cases, and enabled arvioija import in non-local environments. Impact: higher data quality and reliability, automated data workflows, and a more maintainable UI/template framework, delivering faster onboarding and fewer manual interventions. Technologies/skills: data pipelines, scheduling, versioning, error handling; mustache templating, UI templating, page templates; CRUD refactor; environment-aware deployments.
