The GitHub Ruby on Rails monolith is big: nearly two million lines of code and more than 1,000 engineers collaborating on it, to the tune of around 20 deployments every day. To operate at that scale, while providing a performant and highly available experience to the millions of developers who rely on our platform, we dive deep into software development fundamentals. Follow along to see how we build and continually improve the tools you use every day.
