Corvin-Petrut Cobarzan developed and maintained proactive maintenance communications for the ecmwf-projects/cads-messages repository, focusing on documenting the April 29, 2025 maintenance window across CDS, ADS, EWDS, and CEMS systems. Using Markdown for clear and accessible documentation, Corvin updated system status configurations to reflect potential disruptions, such as adjusting CDS severity levels and adding new maintenance session files for ADS and CEMS. The work emphasized traceability through a well-maintained commit history and ensured consistent messaging across multiple platforms. While the scope was limited to documentation, the approach demonstrated attention to detail and readiness in communicating system changes to stakeholders.
