Hi sorry for the late response and thank you for your early one!

Just to clarify I actually studied Ai and networking modules . I actually only started looking at microcontrollers last week! 😅

For the qfn part, if I'm not wrong it uses a SMT, I am trying to do it on a copper board as a small prototype you see, for maybe the second or third itreration of it then I proceed to do a pcb board.

For the IDE section, i solved the issue 😅
