UX Engineer bridging user needs, system logic, and technical implementation — basically making sure people and systems understand each other.

Message

Built interactive systems across physical computing, healthcare, and digital products, focusing on how user actions translate into system logic and technical implementation.

In a tangible interaction project, I built a state-machine architecture and improved sensing accuracy to 90% and response speed by 20% through sensor calibration, signal processing, and iterative testing.

For a shared-wallet MVP, I treated AI coding agents as part of the development workflow: I defined the product rules and system logic, then used agents to support implementation, debugging, and edge-case validation while keeping the core product decisions under my control.
