I am an Director of Engineering at MongoDB. I lead four teams focused on building a large C++ codebase (with Bazel), creating tooling to prove database correctness, and creating the infrastructure for performance testing. We have improved/built tooling to performance benchmark MongoDB. We have measurably increased availability, improved user experience, and decreased noise.Additionally, we were responsible for the transition from SCons to Bazel drastically reducing build times. Finally, I created The Correctness Team responsible for building and maintaining infrastructure to prove database and multi-service correctness.
