I did have a gap in my skills. I've done a bit of operations stuff but never a lot. I had to learn a lot quickly about the operations side of things, learning things like Kubernetes, Docker, and all the Azure offerings fairly quickly. I love it. I love someone else paying me to learn cool stuff. I'd do this in my free time anyway.
I fix it by building random weird projects. Often I'll take the dumbest startup idea I can think of in three minutes and try to build it. It's fun!
