Work experience
Architected and shipped VeraTalk, a real-time AI video conversation platform built with React and Node.js. Implemented WebRTC signaling, adaptive bitrate, and a lip-sync avatar workflow, targeting sub-300ms end-to-end latency and stable performance on flaky mobile networks.
Led full-stack development on GlobeServiceDesk, a React and Node.js platform with WebRTC-based agent–customer video sessions. Built real-time messaging over WebSockets and Redis pub/sub, achieving responsive chat and session resumption with improved latency and CSAT.
Contributed to KaizenFlow, a Node.js and React platform for Japanese manufacturing clients. Implemented REST APIs and WebSocket services handling ~1.2M events per day, and developed operator dashboard components with significantly faster page loads.
