about

Hey, I’m Efren.

You can find me up bouldering walls, on spirited drives or making way too much coffee.

I architect & integrate electrical and electronic (E/E) vehicle systems for Czinger's low-volume motorsport-focused parallel-hybrid supercars.

I used to architect & integrate software systems for Rivian’s electric adventure vehicles, help develop Zoox’s autonomous robotaxi to be safer for riders, design the electronic central nervous system within Faraday Future’s FF91 EV, and engineer prototype vehicles for both small start-ups and large automotive OEMs with Motivo.
