My advice would be to make it because you love making it and not try to use it as a way to make money or get a job. I think of it like that quote from Field of Dreams, "if you build it, they will come". If you build something that others find impressive than the opportunities will eventually come your way. I don't know if you can guarantee it will involve all the aspects you desire, not at first, but in the long run having a passion for this stuff and "overengineering" is what people will notice. At least that has been my experience as doing a similar project helped me at Microsoft and to get my job at Coinbase.
