At work I've got more familiar with Terraform, got started with Kubernetes, and contributed significantly to the infrastructure of a few awesome projects.

In my spare time I've been maintaining my Autospotting pet project, which is maturing nicely, growing a lot and already generated savings in the six-seven digits for its users: https://github.com/cristim/autospotting

I also spent time learning to play guitar, made a habit of practicing and working out on a daily basis and towards the end of the year I became a father.

All in all it was likely my best year so far.
