development around etherium ecosystem

Hello friends.
My question may be duplicate but I don't have much time, I literally googled single time and there was not good answers so I decided to ask directly without any deep searchs so sorry for that.

last 3 month I got interested in blockchain technology and started learning. It was very interesting to learn architectural design behind some of them. ( I touched mostly bitcoin, ether and solana).
At this moment I want to dive deeper in etherium so I need some guidence and advice where to start learning all the development concepts around it. I have experience of software development, mostly in gambling and banking domains ( I am just telling that because I don't want courses that explain for loops or something like that) .
