At TATA Technologies Ltd. (Tata Motors Ltd., on-site), I diagnose electrical, electronic, and mechanical faults across passenger cars, trucks, buses, EVs, and fuel-cell vehicles. I validate OBD-II/UDS diagnostics and use fault injection and component-level testing to investigate issues.

I also validate CAN, LIN, and gateway wiring integrity, and document test findings, fault diagnoses, and removal and refit procedures. My work supports guided troubleshooting, vehicle cybersecurity verification, and HV/EV and fuel-cell bus platform validation.

Previously, at India Kawasaki Motors Pvt. Ltd., I diagnosed and repaired two-wheeler faults. At Bajaj Auto Limited, I validated exterior lighting components and prepared specifications, validation plans, and test reports; I also filed a 2026 patent application for an automotive electrical system.
