To get beta users for our app, we started a free coding group at our local libraries and got a few dozen active users: https://www.meetup.com/San-Jose-C0D3/
I am pretty happy with the outcome and the code quality. The students wrote unit tests with every pull request, listened to feedback, and achieved 100% code coverage in the codebase. Now, after some user feedback and iterations we are ready to give a preview of what we worked on. Any feature suggestions / feedback will become learning opportunities for the next generation of students.
Last month, a rec opened up on my team and I was able to hire one of these students. If I could hire all of them, I would. If anyone here is hiring, please consider hiring these awesome students who worked hard to make c0d3.com possible (I've listed their code contributions and linkedIn profiles): https://github.com/garageScript/c0d3-app/wiki
