At Kilona, I developed and maintained features for VibeMeal, an AI-powered calorie tracker with mobile and web versions. I implemented food analysis and nutrient-tracking flows, personalized AI feedback, and AppsFlyer analytics and attribution.

For an AI Cooking Assistant App, I took ownership of the React Native and Expo frontend, integrated Firebase, and developed Node.js APIs for AI recipe generation. I also integrated LangGraph and LangSmith agents and built speech-to-text user flows.
