During February 2025, Alvaro Meza focused on enhancing CI/CD reliability for the Telefonica/mistica-design repository by addressing a silent failure risk in the design token synchronization workflow. He improved the sync-design-tokens.yml process by adding the -f flag to curl commands, ensuring that workflow dispatch events would fail explicitly on curl errors rather than proceeding silently. This change increased incident visibility and reliability across related repositories, including mistica-web, mistica-ios, and mistica-android. Alvaro utilized YAML and GitHub Actions to implement these improvements, demonstrating a targeted approach to cross-repository CI/CD reliability, though the scope was limited to a single bug fix.
