Hi there! 🎉

My name's Maël and I'm a senior software engineer, currently focusing on developer experience (how to improve developer productivity while making our applications more stable?). I jumped into this role back in 2017 when I joined Facebook after years of startups, then kept doing it after moving to Datadog. As part of my role (and also because I like it and I'm lucky enough to have an understanding family 😉), I contribute a lot to the open-source movement.

If you want to support me, feel free to follow me on Twitter (it gives me a wider reach, and thus makes it easier to promote my project updates), or wait until I finally enable this magic Sponsor button. Also feel free to drop me an email!

I've been Yarn's BDFL for a few years now (since 2017, approximately). More recently I completely rearchitectured and rewrote the software, which has been a huge undertaking as you can imagine. Fortunately, I've been helped in this endeavor by the arrival of new contributors, finally building the community I dreamt of. Speaking of which, we're always open to new contributors, so ping me on Discord if that might be you!

Finally, I'm also the designer and implementer for Yarn Plug'n'Play (PnP) - so if you see me tell you that you shouldn't rely on hoisting, do me a favour and trust me! After all this time, I feel like I could write a thesis about package management 😄

I love to learn by practice, and since I started my journey I touched a bit of everything: full websites, compilers, emulators, terminal interfaces, ... while there's many way to approach software development, I found this one to fit my personality the most. By contrast, I find very hard to follow tutorials or videos when learning new techs!

My two main libraries at this point in time are Clipanion, a CLI framework, and Typanion, a runtime type assertion library. I also have a secret project I hope to show you one day ... one more reason to follow me on Twitter! 💫
