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?
Yeah I was debating putting that info in OP because I’m also unsure of which direction I should go. I have experience in Java, Javascript, Python, database language / querying, systems design, cloud infra, etc. all the foundational stuff of backend devs (+ some full-stack experience).
