Author of Express and Koa

TJ Holowaychuk

TJ Holowaychuk wrote Express, the HTTP framework that defined server-side Node.js for a decade, along with Koa, Mocha, and a long list of smaller tools. He is also known for stepping back from Node entirely and moving to Go, which is visible in the language mix on his account. His profile is a good illustration of how a contribution graph looks when someone's most influential work is largely behind them and has been handed to community maintainers.
