Tomokazu Tantaka contributed to the reearth/reearth-visualizer and related repositories by building robust backend features and improving data integrity across project import/export, multilingual support, and geospatial validation. He implemented GraphQL APIs and Go-based server logic to enable reliable asset management, custom domain support, and advanced layer ordering, while also refining test infrastructure for faster CI and more maintainable code. His work addressed concurrency and database challenges in MongoDB, enhanced data validation for GeoJSON, and streamlined CI/CD automation. By integrating TypeScript and React on the frontend, Tomokazu delivered solutions that improved end-to-end data consistency and expanded user-facing capabilities.

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.
