United States

Message

At Locator X, I developed embedded firmware for nRF52840 Bluetooth and asset-tracking devices using C/C++, Zephyr RTOS, and Nordic nRF Connect SDK. I also developed low-power BLE tag firmware on the Dialog Semiconductor DA14531, integrating motion detection, SPI flash, and power management.

At GPS of Things, Inc., I designed multi-radio tracker firmware spanning BLE, cellular, GNSS, and LoRaWAN, then delivered the AWS IoT back end and customer portal. Earlier at Systech Corp, I implemented embedded applications, Linux and USB components, cellular modem support, and Yocto Project images and SDKs for fielded devices.
