First, I'd like to congratulate you, your parenting skills are obviously awesome, I've started learning Coding/Electronics at the age of 14 but I wish I had started earlier.
I am an Electronics Engineering student, I have 3 years experience with Rpi/Microcontroller programming and 4 years of Coding.
I would love to participate in interesting your child and grow his passion.
Please contact me to discuss this further.
