Harpreet Nandra contributed to the SkillsFundingAgency/dfc-coursedirectory repository by leading major architectural migrations, data import optimizations, and API simplifications over four months. He migrated core modules and provider features to a unified MVC structure, modernized frontend assets, and improved test reliability using C#, ASP.NET Core, and JavaScript. Harpreet enhanced the OnSPD data import workflow with robust error handling, granular logging, and performance tuning, increasing throughput and data quality. He also streamlined the API and data model by removing redundant fields, reducing maintenance overhead. His work demonstrated depth in backend development, database integration, and CI/CD pipeline management for maintainable delivery.

July 2025 summary for SkillsFundingAgency/dfc-coursedirectory: Delivered two major enhancements to the OnSPD data import workflow, strengthening reliability, observability, and throughput. Key work includes robustness improvements to Manual Import ONSPD API with restored HTTP response handling, added comprehensive error handling, and enhanced logging for missing filenames, incorrect file extensions, and general import failures. Additionally, the Onspd Data Importer was enhanced with granular logging, performance tuning, updated tests, larger import chunk sizes (increasing ChunkSize to 10,000), and a refactor of CSV parsing. These changes reduce import failures, improve data quality, and accelerate processing, delivering measurable business value through safer imports and clearer diagnostics.

Month: 2024-11. Delivered a targeted data-model and API cleanup for SkillsFundingAgency/dfc-coursedirectory by removing the Provider Satisfaction fields. Specifically, LearnerSatisfaction and EmployerSatisfaction were removed from the Providers table and the Provider model, along with corresponding updates to query handlers and API responses for course runs and T-Levels. This simplification reduces API surface area and data model complexity, enabling faster iteration and easier maintenance.
