The Inspirational Ignition:
Why I do, What I do?
Drawing inspiration from the depths of the ocean to the expanse of outer space, my fascination with robotics is fueled by a desire to unlock the unknown and harness technology to revolutionize our world.
This journey, influenced by childhood heroes like Kiteretsu (Yes! The cartoon) and Tony Stark (Pure Amazement), has evolved into a dedicated pursuit of advanced robotics, mechanical engineering, and electric vehicle innovation at Johns Hopkins University and beyond.
​
At ELTRA, I took on the challenge of addressing one of the most pressing limitations of electric vehicles: range anxiety. As a Founding Project Engineer - Mechatronics, I led the design and development of the Electric Pusher Trailer Unit, a solution designed to double EV range and transform the future of electric mobility. This involved not just designing and analyzing complex systems like vehicle frames and cooling systems but also integrating critical components such as Ford F-150 axles, UQM motors, and BorgWarner differentials with custom-built systems. The result? A road-tested prototype that marked a significant milestone in the journey toward eliminating range anxiety.
My experience at ELTRA exemplified my commitment to hands-on problem-solving—designing, machining, soldering, coding, and innovating to turn an idea into a fully functional reality. From developing a custom CAN sniffer to spoof VCU throttle signals to engineering a battery enclosure that accommodates Tesla-level safety standards.
​
At the heart of my exploration lies a deep-seated passion for creating robots and systems that do more than just function—they adapt, learn, and thrive in the most challenging environments. My academic and professional projects embody this vision, whether it's enhancing the localization of a Jackal robot in rugged terrain, developing high-fidelity simulation models for UAVs, or building scalable navigation algorithms for deep-sea exploration.
My professional journey has also included significant contributions to the automotive industry at Mahindra & Mahindra, where I led subsystem integration for EV platforms, optimized NVH performance for the XUV700, and reduced build times for prototype vehicles by over 70%. These experiences, combined with my initiative in developing MATLAB algorithms to predict vehicle performance, have demonstrated my ability to innovate within highly constrained environments.
​
Driven by curiosity and a zeal for overcoming challenges, my journey so far has been a testament to my belief in the power of technology to create a better future. As I look forward to contributing my skills and experiences to the fields of robotics, electric mobility, and mechanical engineering, I am excited about the opportunities to push technological boundaries further, exploring new horizons and making meaningful impacts along the way.
This is who I am—an engineer ready to take on the world's most daunting challenges with a toolbox filled with innovation, expertise, and an unwavering passion for robotics and vehicles that move (either autonomously or by our intervention).
