Engineering
Over the course of a year, GitHub’s engineers make millions of commits across all of our internal repositories, process billions of API requests, and run tens of thousands of deployments across the internal apps that power GitHub’s services. We use many of GitHub’s products and plenty of other open source tools to operate at this scale. Here’s an inside look into how we do it.
Fixing security vulnerabilities with AI
