In the summer of 2015, I joined Auro Robotics as a Motion Planning Engineer during their Y Combinator batch, when Sam Altman was CEO. Working directly with the co-founders and initial team, I developed ROS-based local path planning algorithms that integrated GPS and LiDAR data.
Our pivotal achievement was demonstrating the shuttle's autonomous navigation during YC Demo Day, securing $2.1M in funding from Sam Altman and the YC network. This experience honed my skills in rapid prototyping, scalable design, and market-ready tech deployment through persistent iteration.
