Embedded Software

Reliable, efficient embedded software for IoT devices, motor controllers, and signal processing systems.

With over a decade of experience developing embedded software for critical transportation and industrial applications, I specialize in motor control, power electronics, and real-time systems. My embedded software powers everything from electric vehicles to locomotives, ferries to streetcars, and has been deployed in some of the most demanding environments—from Disney theme parks to NASA research facilities.
