## About

As a Deputy Senior Engineer at Delphi\-TVS Technologies, I specialize in diesel engine and vehicle calibration with a strong focus on BS6 emission compliance, drivability tuning, and powertrain system integration\. With 3\.5 years of hands\-on experience, I have worked extensively on EMS\-TCU & EMS\-ESP interface calibration, airpath modeling, emission & RDE optimization, and drivability calibration across MT, AMT, AT & DCT transmissions\. My project experience includes Tata Nexon, Tata Curvv & Tata Sierra BS6 variants — contributing to Tata's first\-ever Diesel DCT program, high\-altitude trials, and ADAS terrain mode calibration\. I hold a Bachelor of Engineering in Mechanical Engineering from Thiagarajar College of Engineering with a CGPA of 88\.6% \. I am currently open to new opportunities in Powertrain Calibration — across OEMs, Tier\-1 suppliers, or emerging EV/Hybrid platforms\.Open to connect\.
