Part of a small team that re-wrote the Healthengine android app from scratch using kotlin, rxjava, dependency injection andretrofit among other libraries to provide users with an awesome native experience. The new app shot up to 4.8 star on the Play Store and the 99.9% crash free rate is due to extensive unit testing and UI testing using our bitrise CI, with a 75% coverage we're doing really well. Also helped write some PHP backend code to facilitate the app, sometimes it's best to let the backend be the source of truth. Looking to apply my learnings on new exiting projects in the future!
