Our repo has around 300K lines of code and more active feature flags at any given moment than we have fingers and toes. As we have moved into a world of continuous deployment with controlled releases, the use of feature flags has become an essential way of writing software.

David Burrowes is a software engineer at Split.io with a decade of experience developing web applications for companies like Box, Delphix, and VMware. Having worked without feature flags, and with clunky in-house feature flagging frameworks, David is deliriously happy to have all of Split's capabilities at his disposal for every project. For fun, and to prove he’s more Star Trek than Star Wars, David likes to randomly quote large sections for Star Trek II: The Wrath of Khan.
