additional services/platforms and cutting ~30–40 minutes of manual work per new platform
deployment while reducing risk of misconfiguration.
• Implemented CI/CD caching for infrastructure pipelines in GitHub Actions, reducing execution time
of long-running pipelines by roughly 40% and speeding up delivery/feedback for the engineering
teams.
