Developed my own iOS application Pick 3 Pro for distribution thru Apple App Store.Pick 3 Pro is a Pick 3 and Pick 4 lottery app that uses statistics and probability to track the short term trends happening for all Pick 3 and Pick 4 games in the United States and Canada.Released to App Store on Jan 24, 2022. Have since released three updates.Some of the highlighted tasks involved in development, release, and current maintenance are:1) Written entirely in Swift2) Paid auto-renewing subscription that integrates with RevenueCat for payment processing.3) Uses Charts package to provide visual cues for tracked stats.4) Uses Realm database to search past draw history for short, medium, and long term trends based on customer input.5) Wrote companion Admin App that crawls the web for the daily lottery results and writes the data to Firebase datastore for consumption by Pick 3 Pro app. The Firebase datastore is shared by Admin app and Pick 3 Pro app. Admin app has write privilege's whereas Pick 3 Pro app has read-only access using anonymous login6) Integrates with Firebase Datastore backend to retrieve the draw history results.7) Integrates with Firebase to receive push notifications with draw results as they happen and at the end of the day to receive alerts on what trends to pay close attention to for the next day's play.8) Integrates with Firebase Cloud functions to receive Web Hooks from RevenueCat in order to track customer subscriptions.9) Integrates with Firebase Cloud function so that when Firebase Datastore is updated push notifications can be sent to users who have subscribed for a particular topic of interest.10) Uses web hosting via Vultr to host website pick3pro.com and integrates with Flarum community software to provide customer support for users.Wow that was a lot to learn and develop in 5 months !!! Especially the Firebase Cloud functions to glue everything together was particularly satisfying.
