What's more, Cloudflare operates within 50 milliseconds of 95% of the Internet-connected population globally (for context, the blink of an eye is 300-400 milliseconds!). We are passionate about making the Internet more secure, reliable, and faster for everyone.
Cloudflare's Engineering teams build and run the software that handles the massive amount of traffic that flows through our network. We also have teams that build the UI and control plane for our software, using modern patterns and libraries in a microservices-based architecture. Technologies include: C/C++, Rust, Go, Lua, Nginx, Go, Python, Typescript, JavaScript and ReactJS.
