Ratheesh R worked extensively on the SkillsFundingAgency/das-apim-endpoints repository, delivering a range of backend API features and enhancements focused on notification workflows, feedback management, and secure telemetry. Using C#, ASP.NET Core, and OpenTelemetry, Ratheesh migrated legacy logging to modern observability, refactored authentication to ApiKey-based flows, and expanded notification and sharing endpoints to support evolving business requirements. He implemented robust unit and integration tests, improved configuration management, and centralized logic for maintainability. His work addressed data integrity, security, and operational efficiency, demonstrating depth in backend engineering and a methodical approach to evolving complex API systems for reliability and scalability.
January 2026: Delivered Framework Certificate API enhancements for SkillsFundingAgency/das-apim-endpoints, enabling robust access to framework certificate data. Replaced the previous learner endpoint with dedicated framework certificate detail endpoints, introduced and evolved query/response models, and refined data models (CertificateType, CourseOption) to support framework certificates. Implemented comprehensive unit tests and performed code cleanup, naming corrections, and path fixes to improve API consistency and maintainability. These changes enhance data accuracy for downstream systems, improve reporting and eligibility checks, and support future feature work with a solid, test-covered foundation.
