I am starting again now with the idea of finishing it by the end of 2023, but I wanted to give it another try here on HN to collect some feedback as my first submission went completely unnoticed.
What you mentioned about backend/frontend is actually very cool. In my original plan I wanted to produce three compendia: 1. Software design 2. Software architecture 3. Tech leadership
Still in my mind, but considering I am yet to complete the first one, it is going to take a while :)
Let me know if you ever go down that road! I would be very curious to read it.
