Spencer was one of the original creators of open-source, cross-platform image editing software GIMP (GNU Image Manipulation Program), authored while he was still in college. He went on to spend a decade at Google, plus two years as CTO of Viewfinder, later acquired by Square.

In 2014, he cofounded Cockroach Labs to back his creation CockroachDB, a cloud-native distributed SQL database.

Database sharding is essential for CockroachDB: “a critical part of how Cockroach achieves virtually everything,” says Spencer. Read up on how sharding a database can make it faster.

Like many engineers who find themselves in the C-suite, Spencer went from full-time programmer to full-time CEO. He says it’s been a “relatively gentle” evolution, but he can always go back.

Like lots of you out there, Spencer started programming on a TI-99/4, the world’s first 16-bit home computer.
