DC Fast Charging & Power Systems Product Development

I develop DC fast charging and industrial power systems end to end — from CAD models and electrical schematics through BOMs and regulatory compliance.

About

I'm an electrical engineer with 3+ years of experience building DC fast charging (DCFC) systems, electrical designs, and industrial power systems. I manage product development from end to end: CAD modeling and electrical schematics through BOM creation and regulatory compliance.

I'm a named contributor on a pending patent for a DCFC station, and I integrate BESS, solar, and supercapacitor technologies into deployed energy systems. My background also spans controls, embedded programming, and industrial communication protocols including OCPP, CAN Bus, and Modbus.
