Most of my learning was on the job, and in building some open-source projects that I have released over the years, for example: - https://github.com/anthonynsimon/bild https://github.com/anthonynsimon/bild - https://github.com/traduora/traduora https://github.com/traduora/traduora I still have a lot to learn, but IMO nothing beats struggling with something for a long time, and pushing along until you're no longer terrible at it. I feel that most of what I know I learned by starting projects on topics I initially new nothing about, and sticking to it. Regarding on the job learning, I have been working with Python/Scala for my full-time job over the past 3.5 years, and that helped too. Specially in terms of running multi-regional services, and the challenges that come with that. We run several applications on Kubernetes using AWS (combined >2k req/s at peak time), and that was a big challenge for me from which I learned a lot. Specially when you're on-call, and one faulty node brings down the entire cluster, that fails over to another region and repeat :)
