Second Project: Add WiFi to Wearable Transdermal Alcohol MonitorGoal: Original device transferred data via RF packets to a base-station (which then uploaded the data to a remote host via cellular connection). Updated product uses WiFi.Project: - Developed a Git submodule shared between 3 processors (one on wearable device, 2 on base-station) that define.

Goal: Company approached me to come back and work for them again (see prior experience below). The specifically needed someone to add new client-requested functionality. Specifically, clients wanted the wearable device to be able to continuously capture photos and audio and stream them to the company’s cloud application.Skills / Tools: See list in prior.

Worked on porting C driver and HAL code to next generation platform for a safety-critical enterprise-class wearable safety device. This device uses an ARM processor, RTOS, GNSS, GPS, Audio, Camera, buttons, and LCD screen to report wearer location during emergency situations to authorized authorities.
