Embedded software developer at StreamLabs building secure AWS IoT flow-meter firmware with OTA updates and rollback.

United States

Message

At StreamLabs, I develop IoT flow-meter controller software on the TI CC32xx platform using AWS IoT and TI-RTOS. I implemented secure OTA updates with firmware verification and rollback to a working image if validation or post-update checks fail.

At TK Elevator, I designed the IoT device architecture and Linux data-collection clients used across more than 100,000 deployed units in the Americas. I also ported elevator software from WinCE to Linux and moved IoT applications from Linux to Green Hills RTOS.

At QuidelOrtho, I led Qt/QML GUI development for viral diagnostic assay workflows on embedded Linux and integrated HL7 and POCT1A communication protocols. I supported software verification and validation for FDA clearance under IEC 62304.
