PROFILE
Carwyn Pelley
Worked extensively on the metoppv/improver repository, delivering features and fixes that enhanced CI/CD reliability, data processing robustness, and documentation clarity. Leveraged Python, YAML, and Bash to modernize environment management with micromamba, standardize input handling through utility functions, and refactor core plugins for maintainability. Improved code quality by integrating Ruff linting and pre-commit hooks, consolidated security checks, and stabilized CI workflows with targeted dependency pinning. Addressed data integrity by hardening NetCDF file saving and permissions, while also refining documentation pipelines and coverage reporting. These efforts resulted in more predictable releases, safer data output, and a smoother onboarding experience for contributors.
