I decided to write a recap of my 2017 because looking back, it was a very important year to me.
I got involved with the Node.js project in 2016 (I was a Node.js user previously, but had not been a contributor until then). In 2017, I started to contribute to Node core and related projects regularly. I was nominated to become a collaborator at the end of 2016. I was a bit surprised to find that my first PR submitted in 2017 was my Node.js core collaborator onboarding PR, which added myself to the README of nodejs/node. (The most important part of onboarding, however, is getting invited into the @nodejs/collaborators team, which also gives you access to the CI. The onboarding PR is more of a formality).
