PROFILE
Zhian N. Kamvar (umass)
Worked on the cdcepi/FluSight-forecast-hub repository, delivering features and stability improvements across data engineering, CI/CD, and workflow automation. Enhanced the CI/CD pipeline using GitHub Actions and YAML to improve build reliability, dependency caching, and reproducibility, while also implementing schema migration and rollback strategies to maintain data integrity during transitions. Developed R scripts for generating hubverse-format data and introduced time-series data logging in CSV to support influenza hospitalization rate tracking and trend analysis. Addressed workflow robustness by refining access policies and conditional logic, resulting in more resilient deployments, improved data management, and streamlined onboarding for contributors in a collaborative environment.

Dec 1, 2024December 2024: FluSight-forecast-hub monthly update highlighting key deliverables, stability improvements, and technical milestones. A Schema Version 4 migration was pursued to modernize data contracts and processing, coupled with a rollback plan to preserve data compatibility and system stability during transitional changes. CI reliability was enhanced by pinning the GitHub Actions runner to Ubuntu 22.04, reducing environment-related build/test failures. These activities collectively strengthen data integrity, deployment reliability, and readiness for future migrations.
