Definitely possible, but not very predictable. I wouldn't bet on your first products earnings anything but with enough experience and focus a 6 month time frame is more than enough to spin up a working product and proceed from there. I haven't spent more than 6 months development time (much less for most) before starting any of the projects that pay for my life right now. That said i spent years without earning anything relevant, trying to get here.
