Become a sponsor to Mateusz Burzyński

Hi! 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 - that has led me to help over 270 repositories with over 1000 pull requests (still counting!) and maintaining few popular repositories. At the moment I take care over:

At the moment my main focus is the first one - XState. I believe that statecharts have too many good traits (like visualization, simulation, up-front modeling, etc) that they are too important to ignore them in your day-to-day development and I hope to make working with them even easier.

Over the past years, I also got expertise in making libraries tree-shakeable (by tooling optimization and code changes), so if you want to take care of that aspect of your JavaScript library - I'm your guy.
