Performance-focused monthly summary for 2025-10: Key features delivered: - Reearth Visualizer: GetAllProjects API enhancements delivering scalable discovery and filtering capabilities. Added pagination, keyword search, sorting by update time and star count, visibility filtering for public/private projects, and topic-based filtering. (Commits: fb1359d6cde98ee4bc22a79de8fe558dac6bbb80; cd9c3425de9dc721ac1279a2956482e0975231ca; 3b8a74bcc9c73ecd67a049f366f34e39f9336f23) - Reearth Visualizer: Project Topics support and metadata migrations for topics as a first-class attribute, including migration of topic data structures and handling of edge cases in metadata conversion. (Commits: 275b4a054b9cc760b0b538eee910ca3b9087a0c0; 1e60c94d9b469185076bd858fa0d495fc829514e; 1ffd63a99ed6caba7a2ed7a5ed01ce2b6c0d7352; 4d89105a898553064835c779523e78fb42dca2e0) - Reearth Visualizer: Star functionality and project metadata refactor to enable star/unstar, centralize metadata, and update sorting to reflect star counts and starrer information. (Commits: e5c4a52236eaa01cc36307b224725ebbd51931f7; 88b7cb1d644fcf485c957225063854a23f2dcf25; 6c933635ddd6b6fe43d259090d74e0f43750fab0) - Reearth CMS: Project Starring feature with backend support to update star_count and starred_by, complemented by end-to-end tests to verify starring, unstarring, multi-operation flows and error handling. (Commit: 5021b2a3d955de770194a8adac333137dd0e70bf) Major bugs fixed: - GetAllProjects pagination correctness fixed to use limit and offset to ensure stable paging and reproducible results. (VIZ-1845) - Metadata topic migrations addressed edge cases: handling empty topics array and proper type transitions to string array, preventing data loss or inconsistent states. (VIZ-1857, VIZ-1875, VIZ-1877) - Metadata migration and project creation adjustments to remove outdated fields, ensuring cleaner project metadata and preventing stale references. (VIZ-1861, VIZ-1859) Overall impact and accomplishments: - Substantial improvement in project discovery and user experience through robust APIs and topic-based filtering, enabling faster, more relevant results for end users. - Improved data integrity and analytics readiness with centralized star counts and starrer tracking, supporting better engagement metrics and ranking. - Cross-repo collaboration between Visualizer and CMS enabling consistent starring semantics and end-to-end reliability, backed by automated tests. Technologies and skills demonstrated: - Backend API design and optimization (Go) for scalable endpoints, pagination, search, filtering, and sorting. - Data modeling and migrations, including topic metadata handling and migration-safe transitions between data structures. - Feature flagging for visibility fields, topic-based filtering, and star logic, plus test-driven development with end-to-end tests. - Cross-repo coordination and deployment hygiene to ensure consistent user-facing behavior and analytics across Visualizer and CMS.

In September 2025, completed a schema migration for project metadata in reearth-visualizer. Added new fields to the project collection (created_at, topics, star_count, starred_by) and implemented a migration to populate them with default values. Included tests to verify functionality and idempotency, improving data quality and analytics readiness while reducing manual data maintenance.

August 2025 (reearth/reearth-visualizer) — Focused on policy-driven UX, localization consistency, and UI polish to improve business outcomes and developer efficiency. Key features delivered: - Policy-driven private project creation and visibility controls: Added dynamic workspace policy checks for private project creation via GraphQL, with sensible defaults when policy data is missing. Integrated policy validation into the project visibility modal and centralized policy handling with a reusable hook to enhance maintainability and user experience. - Localization and Language Handling Improvements: Strengthened localization across the UI with default language fallbacks, a useLang-based language value flow, and translations/terminology updates to ensure consistent localization. - Dashboard UI Enhancements and Polish: Improved dashboard navigation and UI polish, including language-based documentation links, safer external links handling, and general UI cleanups in dashboard and sidebar. Major bugs fixed: - Fixed private project creation checks and visibility logic to ensure accurate policy enforcement and UX consistency. - Corrected disabled button state logic for project visibility changes. - Localization fixes: added language declaration fallback and refactored language value imports to prevent regressions. Overall impact and accomplishments: - Reduced policy risk by enforcing policy-driven creation and visibility at both UI and data layers. - Improved localization consistency and onboarding experience for multilingual users. - Enhanced maintainability through centralized policy handling and targeted UI refinements, enabling faster future iterations. Technologies/skills demonstrated: - GraphQL policy checks, React hooks and custom policy hook, i18n/localization practices (useLang, translations), UI polish, and secure external link handling.
