Background

About

I earned dual BSE degrees in Electrical Engineering and Computer Engineering from the University of Michigan-Dearborn. My work connects controls, instrumentation, embedded systems, automotive validation, circuit analysis, and robotics.

The value I bring is practical execution: verify the setup, check the signal, isolate the fault, document the evidence, and keep the system reliable.
