About this session
Our monorepo CI took 40 minutes on a good day. This talk walks through how we cut it to 6 minutes with content-addressed caching, remote execution, and a test-selection model — including the two migrations that failed first. You'll leave with a decision framework for which incremental-build investments pay off at which repo sizes, and the graphs to convince your platform team. Updated: now includes 2026 benchmark data. This session now includes a live demo of remote build caching.
Speaker
Priya Raman is a Principal Engineer at Latticework Systems where she leads the build-tooling platform team. She previously maintained the open-source task runner 'gantry' and has spoken at over a dozen developer conferences on build systems, CI reliability, and developer productivity metrics.
