Mobile + Backend
MindMitra
Cognitive-wellness app (iOS + Android)
MindMitra (formerly CognizenX) is a cognitive-wellness app built with DePauw Neuroscience. I led a three-engineer team decoupling AI and data workflows from the shipped React Native client onto a dedicated Vercel/MongoDB backend—isolating ML updates from mobile release cycles while delivering iOS and Android builds with telemetry-driven spaced-repetition scheduling.
