I use Perl at work but have been working on a side project using Django and Angular to 1) learn/keep up with the languages I'm interested in and 2) potentially turn it into a business. I'm sure there are tons of things wrong with it, but I know I'm learning a lot just by forcing myself to figure things out.
One problem, though, is that I may start looking for a new job soon. I don't want to make this open source since I may try to sell this at some point. If you look at my Github you won't see a lot of activity even though I'm working on this every single day. I know employers are interested in seeing that you're working on something though. How do I make sure I don't get looked over?
