Yes, it is doable, but if you're like me (similar background in software engineering) you will probably have to stop thinking about it as a software engineering problem and think about it as a 95% business problem. Who are your customers, why would they buy your stuff and not the competition, who even is the competition, how much money does acquiring and keeping a customer cost, etc etc. If you really need inspiration, watch a few episodes of Dragon's Den and pay attention to the questions they are asking.
