In addition to recent C#, database, and Amazon Web Services management for a client lately, I'm also reworking their mobile app. The existing app uses C# and Xamerin, which makes for a fine, but heavy cross-platform app, but it also uses an older version of MvvmCross. This old version doesn't work with iOS 9's recent enforcement of 64-bit libraries, and so something needs to be reworked. Since they weren't really happy with the current direction, we though we'd start over and use something a little different.
This web app turned native app is coming along nicely, will solve issues of a split codebase, and still is able to communicate with a back-end server. Perhaps I'll post pictures when the app is public.
