DESCRIPTION: At Flexcar, our CI/CD pipelines didn’t start out fast or smooth. Early on, we were stuck with a clunky release process built around long-lived release branches, and pipelines that took 30–45 minutes to complete. Iterating quickly was painful, and merging multiple changes in succession was nearly impossible. Over time, we rethought how our pipelines worked, moving to tag-based release builds, experimenting with merge trains, and eventually introducing optimizations like conditional native builds. Today, our typical pipelines complete in just 6-7 minutes for most changes, while still enforcing robust checks like linting, TypeScript compilation, and automated tests. This talk is a story of that journey: the challenges we faced, the tradeoffs we made, and the lessons learned that helped us make our pipelines both faster and more reliable.
