Over a 13-month period, Stapel developed and maintained an automated meeting reporting system for the gammapy/gammapy-meetings repository. He engineered Python scripts and GitHub Actions workflows to generate weekly README reports that summarize pull requests, issues, agendas, and meeting details, each annotated with timestamps and contributor metadata. His work included automation of environment variable management, secret handling, and dependency management to ensure secure and reliable CI/CD pipelines. By integrating Markdown and YAML for documentation and configuration, Stapel streamlined reporting, improved governance, and reduced manual effort, enabling transparent, auditable meeting records and accelerating onboarding for new contributors within the Gammapy project.
