June 2025 monthly summary for wri/terramatch-microservices. Delivered targeted enhancements in media organization and cross-service cohort analytics, translating into clearer asset management and data-driven dashboards. Implemented Project Report media collections to categorize tree planting uploads, soil water conservation uploads, and related photos, enabling superior media governance and reporting. Enabled multi-cohort filtering across DTOs, services, and dashboards by supporting arrays of cohort strings and updating query logic to utilize multi-cohort operations (Op.and) and JSON containment. Updated tests to cover the new multi-cohort scenarios. No critical defects identified; maintenance work focused on aligning tests and documentation with the new capabilities. Technologies demonstrated include DTO/schema updates, multi-cohort query design, JSON-based filtering, and expanded test coverage, contributing to maintainability, scalability, and business insight.
