How Uber halved monorepo build times with Buildkite

Uber's engineering team faced the challenge of reducing monorepo build times. By transitioning from using *Make* and *go build* to Google's Bazel, they optimized their workflows significantly. Subsequently, they integrated Buildkite, allowing more dynamic, parallel, and containerized builds. These changes led to efficiency gains, improved developer productivity, and faster turnaround times for commits. They also addressed performance bottlenecks through Git checkout optimization, reuse of containers, and enhanced caching strategies. Uber's implementation of Buildkite resulted in better CI/CD processes, contributing to a more seamless developer experience.
