About Me

As a Robotics Engineer with over 7 years of experience, my career has been driven by a passion for developing innovative autonomous systems and computer vision applications. My expertise spans from advanced navigation algorithms for autonomous vehicles to pioneering vision-based systems in agricultural robotics. I've engineered collision avoidance solutions for drone fleets and warehouse robots, achieving up to 99.9% accuracy, and led projects that increased industrial automation efficiency by 80%. My journey, marked by impactful roles at Virginia Tech Transportation Institute, Oregon State University, and IIIT Hyderabad, showcases my ability to bridge cutting-edge research with practical implementation. I've contributed to projects for industry leaders like Collins Aerospace, Intel, and Fujitsu, pushing the boundaries of what's possible in robotics and AI. I'm committed to advancing the field of robotics, leveraging my diverse skill set in C++, ROS, and machine learning to solve complex real-world problems. With each project, I aim to create solutions that not only meet current needs but also pave the way for future innovations in autonomous systems and robotics technology.
