A few words about yourself

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