I’m a mid-level backend dev, ~3 years YOE. I wanted to seriously start thinking about expanding my skillset and learning new stuff / new technologies outside of my daily tasks. But I’m unsure of how to start, how to decide, what would be most helpful to my career, etc. Any advice?
I am currently learning Nix and NixOS. It’s a huge rabbithole with a steep learning curve, but I like it so far. I’m not sure if it can be of any value for you though.
