Worked on the finnishtransportagency/geoviite repository to enhance both frontend stability and backend API reliability. Addressed map layer rendering issues by implementing a concurrency guard in React and TypeScript, ensuring only the initial data fetch creates an operational points layer and preventing race conditions during asynchronous loading. On the backend, focused on improving API contract quality using Kotlin and Spring Boot by introducing integration tests for OpenAPI validation, aligning Swagger annotations, and expanding test coverage for dispatcher types. These efforts reduced contract drift, improved documentation clarity, and strengthened integration confidence for API consumers, contributing to a more robust and maintainable codebase.

May 1, 2026May 2026 summary for finnishtransportagency/geoviite focusing on correctness and stability of map layer rendering. Implemented a concurrency guard for the Operational Points Layer creation to prevent race conditions during area placing. This ensures only the first data fetch is honored while data is loading, avoiding duplicate layer creation and improving UI reliability across async flows and React StrictMode scenarios.
