I enjoyed the article. Kudos on rewriting your server to be more performant and efficient. It's amazing what a motivated dev can do in a weekend, and it's a great reminder of how much room there often is for optimizing.
Thanks James. I wish it hadn't been in a panic mode, but it worked out well and the users have told me they really like the new backend. The Mobile Backend Starter was a great starting point, but I needed something optimized for my app and didn't want to disappoint new users. Passionate users really are a great motivator.
