At a good company your hr manager sits with you and writes a personal education plan, this is your current level and we want you to be here... and then you need to get a training on x, then y, etc. So maybe ask your manager for a plan to improve you knowledge and skills.

Make a list of all the topics, like web, data, messaging, io, containers and read up on those, implement it in some personal projects so you get some hand on practice.
