About Me

AI shouldn't feel like technology —
it should feel like instinct.

🧠

Edge AI

Bringing intelligence to the device with edge inference powered by CoreML and ONNX Runtime. No cloud latency, no privacy trade-offs. Works on iOS, embedded, and beyond.

⚡

Real-Time IoT Systems

Shipped Taiwan's public bike-sharing app and a customized bike monitoring system for 120K+ daily users, real-time BLE telemetry, GPS tracking, and AWS IoT cloud integration.
