The brunt of my application was built a month ago (did some traveling/moving and life happened) and there have been some areas of my back and front end that worked fine for a single demo account but had zero capability of scalability. Monday I mapped out everything that needed doing, got started and realised there was a bunch of other stuff than I needed to do before I could even get to what I thought I could do. But yesterday with a fresh head, I managed to make some serious progress and really get the app into a much better place.
After a month away from code I was worried I'd forget everything, but fortunately its much of the remembering how to ride a bike mantra! Anyway... time to bug hunt!
