For anyone who wants to go down that path — I recommend reading (or listening to) "Build" Tony Fadell:

https://www.buildc.com/the-book

Fadell worked in the R&D department of various companies you may have heard of such as Apple, Google, Sony, Philips, Motorola, Toshiba... as well as others you likely haven't heard of (because they were moonshots that explode mid flight - one tried to invent an iPhone in 1990 when touch screens were shit, networking was wired, and batteries were disposable. Talk about ahead of it's time). That failure wasn't wasted - a lot of the mistakes they made were avoided years later when he was leading one of the teams that invented the iPhone (not from scratch, but by learning from past work).

He's now basically retired and spends his time advising the next generation, but that book covers all the basics. It really is a gift to the billions of people who can't ask an experienced product developer for advice. And if you are lucky enough to be able to ask, the book will give you enough knowledge to avoid asking stupid questions.
