Building language learning app.
I worked on a language-learning app where I built the flagship “Call with Air” feature—an AI-powered conversational practice system that lets users improve speaking skills in real time. My work included integrating real-time audio/video streaming, developing a lip-sync animation pipeline with Core Animation and Metal to bring the interactive UNA character to life, and connecting the front-end with backend AI models.
