Andrew Tarr

Andrew Tarr enhanced the WestDAAT repository by refactoring its data access and validation layers, focusing on reliability and maintainability. He extracted and scaffolded Entity Framework database contexts, integrated a validation engine into asynchronous pipelines, and improved error handling for clearer diagnostics. Using C#, TypeScript, and .NET, Andrew reorganized project structure, standardized code style, and introduced shared libraries to support modularity and testability. His work included dependency injection cleanup, expanded integration testing, and type-safe API surface refactoring. These efforts reduced build fragility, improved data integrity, and established a scalable foundation for future development while maintaining low-risk, well-scoped changes.

December 2024 performance summary for WestDAAT (WSWCWaterDataExchange/WestDAAT). Delivered a solid foundation for reliable data access and testability through EF/DB access refactor and context scaffolding. Advanced testing maturity with integrated validation engine, enhanced error handling, and expanded test infrastructure. Brought in shared project structure from WaDE2 and introduced a shared resolver with initial tests, improving modularity and resilience. Strengthened CI/build stability by DI cleanup, test wiring fixes, and NuGet version synchronization. Established a scalable API surface with type-parameter support and folder restructure to enable flexible service interfaces. These efforts reduce build fragility, improve data integrity, and enable faster CI feedback and richer quality signals.
