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.

Deputy senior engineer at Delphi-TVS, Apr 2025 - Present · 1 yr 4 mos, Chennai, Work Experience — Delphi-TVS Technologies Ltd Deputy Senior Engineer — Powertrain Calibration June 2022 – Present | Chennai, India Responsible for end-to-end diesel engine and vehicle calibration for BS6 passenger vehicle platforms at Delphi-TVS Technologies, supporting Tata Motors programs. Engine Calibration: Performed airpath modeling, PID-based actuator control for EGR, VGT & ITV, smoke limit AFR estimation, after-treatment calibration and engine performance validation for 1.5L 4-cylinder diesel engines. Vehicle Calibration: Led drivability calibration across MT, AMT, AT & DCT transmission variants. Handled emission & RDE optimization, EMS-TCU and EMS-ESP interface calibration and validation, and software testing. Key Projects: Tata Nexon BS6 Facelift (MT & AMT), Tata Curvv BS6 (MT & DCT) and Tata Sierra BS6 (AT) — 1.5L diesel variants. Notable Contributions: Played a key role in Tata's first-ever Diesel DCT program, ensuring functional integration and drivability performance from ground up. Developed new software logic to improve creep and take-off behaviour in gradient conditions. Delivered ADAS and terrain mode calibration for improved safety and off-road performance. Participated in high-altitude trials for turbocharger protection and drivability assessment. Conducted jury-based drivability evaluations and fine-tuned calibration based on feedback. Tools & Software: INCA · VISU · AVL Concerto · AVL PUMA · MATLAB/Simulink · NI Diadem · UniPlot · DDS Flasher · Silver Scan
