Summary
By Aaron Friel, Taylor Blau, and Ted Nyman, Members of Technical Staff. Over the past year, the size and demands on their monorepo have increased at a staggering pace. The team built Pando, a new backend for Git repositories, without interrupting any engineering work or changing how their team uses Git. The team met these goals while retaining compatibility with the Git protocol and client, enabling both their engineers and agents to seamlessly adopt Pando into their existing workflows.
