Muhammad Hassan developed and enhanced a suite of REST and GraphQL APIs for the dotCMS/core repository, focusing on asset permissions, tag management, and publishing workflows. He implemented robust backend solutions in Java and Spring Boot, introducing features such as bulk operations, advanced filtering, pagination, and detailed error handling. His work included designing versioned endpoints, improving API contracts for clarity, and ensuring security through validation and permission checks. Hassan maintained high reliability by expanding integration and unit test coverage using JUnit and Postman, while also updating OpenAPI documentation. These contributions improved data integrity, workflow efficiency, and platform governance for enterprise users.

Feb 1, 2026February 2026: dotCMS/core delivered a focused set of reliability and API-clarity improvements around tag management and publishing workflows, backed by strong test coverage and documentation updates. Key outcomes include a critical fix to tag visibility in the v2 tag update flow, an API contract improvement for tag creation/import to clearly report created vs. duplicates, and a new bulk purge endpoint for publishing jobs with safeguards. Key features delivered: - Tag visibility bug fix in PUT /api/v2/tags/{id}: Correctly resolve tagStorage so updated tags are stored and queried by the effective site ID, preventing invisible tags after updates; cache invalidation now also occurs when host_id changes. Integration tests (TagResourceIntegrationTest) validate create, update, and list flows with proper tagStorage resolution. - Tag creation/import API duplicates handling improvement: POST /api/v2/tags now returns separate created and duplicates lists; POST /api/v2/tags/import tracks duplicateCount separately from successCount; Postman tests and contracts updated accordingly. - Bulk purge of publishing jobs by status: New DELETE /v1/publishing/purge endpoint with safe statuses, in-code validation, and Swagger documentation; includes 7 integration tests to ensure safe operation and data integrity. Overall impact: - Maintains tag visibility across site changes and tag updates, improving data integrity and admin confidence. - Improves API clarity and workflow efficiency for tag management by making duplicates explicit and trackable. - Reduces risk of accidental data loss with a controlled bulk purge mechanism for publishing jobs; boosts operator productivity through better tooling and test coverage. Technologies and skills demonstrated: - REST API design and versioned endpoints (v2/v1) with proper request/response contracts. - Backend logic changes in TagFactoryImpl.java (tagStorage resolution, cache invalidation) and caching considerations. - Test-driven development through integration tests, Postman test updates, and test coverage expansion. - Documentation improvements (Swagger) to reflect new behaviors and endpoints. - Collaborative development evidenced by co-authored commits and cross-feature integration.

Sep 1, 2025September 2025: Delivered substantial API enhancements for dotCMS/core, focusing on Tag API enhancements and GraphQL Page API parity. Implemented robust tag listing with filtering, pagination, and sorting; improved error handling and documentation; introduced export (CSV/JSON) and a CSV template for imports; aligned GraphQL Page API with REST by adding canSeeRules. Strengthened reliability with detailed error reporting and statistics around tag imports, and improved endpoint documentation. These changes increase data accessibility, reduce onboarding friction for tag management, and ensure consistent permission checks across REST and GraphQL.
