May 1, 2025May 2025 monthly summary for geoadmin/service-stac: Focused on improving search relevance and data quality by hiding expired items, implementing a feature-flag-driven rollout, and strengthening test coverage. Delivered a consistent filtering order across endpoints, refactored the active-item filter into a reusable function, and added an expiration-aware test item to validate behavior with future expiration dates. All changes are aligned with PB-1635 and tracked via commits in the repository.

Jan 1, 2025January 2025: Delivered end-to-end ingestion enhancements for geoadmin/service-stac, focusing on scalable batch processing, robust error handling, asset support, and validation resilience. Key features include a new ItemListSerializer for batched item creation with upsert semantics, a POST endpoint to create items within a collection with precise error codes (400 on duplicates, 404 on missing collections), asset support in STAC items (including optional assets), and safeguards to skip validation when initial_data is absent to preserve existing tests. These changes increase ingestion throughput, improve data integrity, and streamline collection item management. Tech stack highlights: Django REST Framework serializers and views, upsert logic, comprehensive test coverage, and asset parsing. Business impact: faster bulk ingestions, reduced manual item updates, and more flexible item payloads for clients.

Dec 1, 2024December 2024 monthly summary for geoadmin/service-stac: Key feature delivered: documentation for the new bulkUpsertItems endpoint enabling bulk creation/update of multiple features within a collection. Also completed API consistency improvement by renaming the 'items' field to 'features' in OpenAPI specs to align with getFeatures. No major bugs fixed this month. Business impact: improved API usability for bulk data management and clearer integration contracts, reducing onboarding time for clients and minimizing payload confusion. Technologies/skills demonstrated: API documentation (OpenAPI), RESTful design, naming conventions, version-controlled documentation, and cross-team collaboration on API standards.
