Medical IoT gateway
Firmware for a home health hub that connects several Bluetooth medical devices at once, processes heart-rate data on the device, holds readings through network outages and updates itself securely over the air.
Technology that looks after people quietly. I build the firmware and do the research behind it.

Production firmware for connected medical and sleep-monitoring devices.

Moved a pressure-sensing mattress to Zephyr RTOS with on-device posture and sleep classification, and cut its power use enough to stretch battery life from months to years.
Reverse-engineered an undocumented label-printer protocol and shipped a native macOS driver for it.
Everyday sensing and machine learning, for earlier and gentler health monitoring.
IoT and AI systems that track heart rate and daily activity continuously.
Unobtrusive monitoring that helps older adults stay safe at home.
Earlier detection of disease, and of fraud in health systems.
Energy use and performance in the networks connected devices rely on.
