Hey there 👋, I'm Matt Phillips.

I'm a software engineer who is passionate about open-source software, functional programming, and testing. I'm a perpetual learner who loves sharing my knowledge on all things code, career development and building products.

I currently maintain multiple open-source packages that I have authored which are downloaded millions of times each month and most notably help maintain Jest and the Jest Community.

I also share my experiences over on my blog. You can expect to learn more about Typescript, Node, React, Testing, and Functional Programming – with some content on career development and founding products thrown in too.

If you share my love for writing Javascript / Typescript and testing your code with the best tools out there, that bring the best developer experience, then please consider sponsoring me on Github. Your sponsorship will help me to spend more time building new features, writing documentation, bug fixing and producing content to help write better quality code that is maintainable, testable and scalable.

Thank you for considering to sponsor my work. 🙌
