Getting ready for the real world

Hey, im a senior at a T10 school with a full time job at a FAANG+ company lined up. I have great grades and some experience coding, but I feel like I could be more knowledgeable about tech and more experience with projects/building my own things.

I’m very good with Java/python/Go/SQL, but I have minimal frontend, devops, cloud experience. I would like to change that, as I want to eventually work at a startup. I just want to put myself in the best position to succeed as an engineer.

Odin project? Udemy? Roadmap? Where to start?! Help
