PROFILE
Kathryn Mazaitis
Kathryn Mazaitis developed and maintained the pudl-archiver repository, building robust data archiving pipelines focused on energy datasets. Over four months, Kathryn engineered features such as per-year data partitioning, automated metadata generation, and checksum-verified uploads to ensure data integrity and accessibility. She refactored core components for reliability, introduced asynchronous workflows using Python and Playwright, and enhanced CI/CD automation with GitHub Actions and shell scripting. Her work included strengthening error handling, improving logging for diagnostics, and streamlining packaging for deployment. Kathryn’s contributions demonstrated depth in backend development, automation, and testing, resulting in a resilient, maintainable, and scalable data archiving solution.

23 Commits • 14 Features
Jun 1, 2025June 2025 (2025-06) focused on reliability, test automation, and developer enablement for pudl-archiver. Key outcomes include: - Checksum verification with automatic retry for uploads to prevent mismatches and reduce 502-related failures, improving data integrity and user experience. - Migration and hardening of the test suite to Playwright across FERC714 and FERC2, with Pixi integration and environment/dependency cleanup to improve reliability and test coverage. - Enhanced diagnostics and logging for zipfile downloads and PDF/HTML edge cases, enabling faster debugging and greater resilience in production workflows. - CI/test stability improvements: restructuring tests, improved timeout handling for page.goto, and fixes for filename collisions and blocked downloads in epapcap. - Documentation improvements: Pixi README updates to guide integration tests, facilitating onboarding and consistent testing.
