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 and mechanical engineering at Johns Hopkins University.

Here, my academic and professional endeavors have not only expanded my technical expertise but also reinforced my commitment to innovation and problem-solving.


At the heart of my exploration lies a deep-seated passion for creating robots that do more than just function in controlled environments—they adapt, learn, and thrive in the most challenging conditions. My work, ranging from the precise kinematics modeling and simulation of UR5 robots to the development of advanced navigation systems for mobile robots, embodies this vision. Each project, whether it’s enhancing the localization of a Jackal robot in rugged terrain or developing high fidelity simulation models for UAVs, is a step towards bridging the gap between theoretical concepts and real-world applications.


My professional journey has also been marked by significant achievements in the automotive industry, where I led the integration of novel electric vehicle technologies at Mahindra and Mahindra. This experience was enriched by my initiative in developing MATLAB algorithms to predict vehicle performance, showcasing my ability to innovate within the constraints of the commercial automotive sector.


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 field of robotics 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.
