Featured APP


Over the years I have developed and worked on several apps.  First using IonicFramework and Cordova I built a craft beer, coffee and dispensary mapping app for the US and focused on Denver, CO.  I have also build out the backend API for a golf training app.  Have worked on a native iOS and Android beer passport app.  I have recently worked on two beer apps and one insurance app using the modern Expo / React Native framework.  BrewBench Monitor was launched in 2020, Brewer’s Friend launched in 2021, Insurance XDate in 2022, Bidnapper and EZsniper Cordova conversion in 2023.
