A few of us at work had a coding sprint and came up with this. It's running on Heroku, uses Rails with Bootstrap, and sidekiq for emails (using redistogo through Heroku).
We learnt a bunch of stuff along the way: We sometimes had issues with running two remotes, if someone forgets to push to one of them Working with a Google Hangout open in the background so we could talk to one another (we're all remote) made it easier to avoid possible merge conflicts - "I'm working on this file, don't touch it!" Keep it simple - plaintext emails, simple architecture, ignore "that would be a cool feature" features
We're planning on running one-or-so-day sprint sessions every few months. Any pointers for how we can be more efficient?
