My name is Mateusz Burzyński and I'm a JavaScript developer focused on React ecosystem. I'm also a big OSS enthusiast. I believe that node_modules is not a black box and I dive into it frequently - that has led me to maintain a few popular repositories like XState, Emotion, Changesets, Redux-Saga. Recently, I also started to contribute to TypeScript itself.

Kelli is a fullstack engineer based in Seattle, WA and working at Sourcegraph to build tools that improve how we work with code. When she's not consuming boba, aka bubble tea, you can usually find her evangelizing TypeScript at yet another developer meet-up, advocating for women and underrepresented folks in tech, or nagging her teammates to update the docs.
Lenz Weber-Tronic works as Senior Staff Software Engineer at Apollo GraphQL, where he is part of the team maintaining the Apollo TypeScript Client.
He is a maintainer of Redux Toolkit and if he’s not currently trying to summon elder gods with weird TypeScript incantations he can usually be found on StackOverflow answering questions on Apollo and Redux usage or opening random PRs on GitHub.
