30+ year old electrician with a family living in Hawaii wants a new career in software dev? Maybe head over to Zuckers compound?
Anyways, I would say "Don't quit your day job" and get working on a side hustle in software dev, if they like android dev then they should start there. Find a niche that they can offer a service or product and promote the hell out if it.
I still find it incredible that someone working as an electrician in Hawaii would want to change careers. I guess it's true that "You don't know what You have until it's gone and the grass is always greener"
