Witek Poreda contributed to multiple SkillsFundingAgency repositories, delivering features and fixes that improved data integrity, onboarding, and analytics for apprenticeship platforms. He enhanced backend workflows in das-commitments and das-providercommitments using C#, ASP.NET, and Entity Framework, implementing robust validation for CSV uploads and refining data models to enforce compliance. Witek introduced analytics payload enrichment and cross-repo alignment for Google Analytics tracking, enabling better user segmentation. He also strengthened code ownership governance and documentation in das-apim-endpoints, supporting maintainability and onboarding. His work demonstrated depth in backend development, test-driven approaches, and cross-team collaboration, resulting in more reliable and maintainable systems.

September 2025 monthly summary: Key analytics enhancement delivered across two repos to strengthen data-driven decision making. Implemented LevyFlag extraction from user claims and inclusion in the Google Analytics data payload, enabling granular user segmentation and improved reporting. Impact highlights: - Added LevyFlag to GaData and wired through to the GA tracking script in both the employer accounts and employer commitments v2 repositories, enabling cohort analysis by LevyFlag at measurement time. - Achieved cross-repo alignment of GA data payloads, ensuring consistent analytics across platforms and simplifying reporting pipelines. - Reduced data gaps for LevyFlag-based analysis, enabling more accurate attribution and business insights related to levy-enabled user segments. Technologies/skills demonstrated: - Data modeling and payload enrichment for Google Analytics - Claims-based data extraction and serialization - Cross-repo coordination and PR-driven development - GA tracking integration and analytics-driven reporting

August 2025 was focused on strengthening code ownership governance across four DAS repositories and laying the groundwork for enhanced data filtering in learner and commitments data. Key governance work established clearer ownership by adding @witpo to CODEOWNERS for core source code paths, improving review accountability and response times. In parallel, we initiated filtration capabilities to support more precise data retrieval (start month/year and start date) in the provider commitments and API endpoints, setting the stage for improved reporting and analytics. No explicit major bugs fixed this month; the work delivered reduces delivery risk and improves maintainability, security, and collaboration across teams.

In July 2025, delivered a focused fix in SkillsFundingAgency/das-employercommitments-v2 to restore reliable cohort details navigation by renaming the route from 'Details' to 'CohortDetails' and updating tests accordingly. This resolved a broken cohort details link, strengthened the test suite, and improved user experience. The work demonstrates routing discipline, test-driven updates, and solid Git traceability.
