Taking advantage of the well-known CSDIY and Claude’s suggestions for my current situation, I’ve decided on my focus for the next couple of months.

Order does not matter

Neetcode: https://neetcode.io/courses

Start with the basics. After finishing, review and practice through leetcode until reaching 150 solved. Next step go for advanced

Networking: https://sp25.cs168.io/

Networking is so important for infrastructure work. I realized this after working on mts-feed, which really exhausts me

C++: https://web.stanford.edu/class/cs106b/

You’re an academism, learn by a course! Do all the homework!

Docker: https://docker-curriculum.com/

Second tutorial after Docker 101

PostgreSQL: https://www.coursera.org/specializations/postgresql-for-everybody

This is very fundamental my friend, you MUST know it

Redis: https://realpython.com/python-redis/

Some familiarity would be enough
