Mindstrong

Mindstrong's main iOS product is a data collection platform embedded into a keyboard extension. While working there, developed that keyboard's autocorrect accuracy to rival that of Apple's keyboard. In order to do so, performed deep research into academic papers, and performed additional deep research (via decompilation and assorted hacks) into Apple's implementation.To improve patient adherence, decreased the keyboard's startup time by a factor of 10 through dylib hacks and optimizations.Implemented many of the things that move an app from a proof of concept to a real product: CI, code linting, analytics, login flows, kill switch, HIPAA adherence, push notifications, localization, and so on.And finally, architected and build a new app, Care, intended for care providers.
