Tomokazu Tantaka contributed to the reearth-visualizer and reearth-classic repositories by building robust backend features and improving data integrity across project import/export, multilingual UI, and geospatial validation. He implemented GraphQL APIs and Go-based server logic to support asset URL handling, custom domain extensions, and batch layer reordering, while also enhancing MongoDB-backed pagination and filtering. His work included refactoring test infrastructure for faster CI, fixing CI/CD automation with goreleaser, and ensuring accurate data serialization and validation for GeoJSON assets. Through careful schema design and end-to-end testing, Tomokazu delivered scalable, maintainable solutions that improved reliability and streamlined data workflows.
January 2025 monthly summary for reearth/reearth-visualizer: Four major capabilities delivered across testing, data modeling, domain support, and geospatial validation. The work improves test reliability and CI speed, expands API capabilities for sketch layer properties, extends domain deployment options, and strengthens geospatial data integrity. Together, these changes accelerate release velocity and reinforce data quality, leveraging Go-based server code, GraphQL APIs, and frontend-backend integration.

December 2024 monthly summary: Delivered stability enhancements and extended layer management capabilities across two repositories. In reearth-classic, fixed core data representation and release reliability: (1) Widget UI padding now correctly reflects nil in JSON, preventing rendering/data issues, with tests updated; (2) CI/CD release pipeline stabilized by fixing goreleaser invocation. In reearth-visualizer, introduced a robust layer management feature: Chainable reordering of NLS layers with a new index field and batch update capability (updateNLSLayers), along with updates to GraphQL schema, resolvers, use cases, and data models to support persistent ordering. Overall, these efforts improved data integrity, rendering fidelity, and release reliability, while expanding end-user capabilities for layer organization. Tools/tech: Go backend, GraphQL mutations and schema, data modeling, test maintenance, and CI/CD automation with goreleaser.
