Automotive
Demonstrated advanced electric drive technology inside a mid-size SUV with high refinement and show-car quality. Work involved reverse engineering all Tesla interfaces, redesigning front and rear subframes, fabricating custom half-shafts, and building plug-and-play high- and low-voltage harnesses.
Automotive
Integrated electric drive technology into a full-size pickup truck without major chassis modifications. Engineered a compact under-hood auxiliary system, a custom battery enclosure for chassis fitment, high- and low-voltage harnesses, and a supervisor/gateway module for torque management.
Automotive
Reviewed and corrected item definitions and hazard analyses (HARA) to achieve compliance with ISO 26262. Prepared safety goals, fault tolerant time interval (FTTI) calculations, fault tree analyses, design failure mode and effects analyses (DFMEA), and safety concepts.
Automotive
Developed a safety-critical drive-by-wire control system using disciplined two-week sprints. Structured requirements, coded the control software, executed verification and validation testing, performed bench testing, and supported full vehicle integration.
