About me
I'm Harry Lonsdale, an undergraduate student in Mathematics - Computer Science at UC San Diego graduating December 2025. This is my portfolio documenting my work. Check out some of my projects, or scroll to the bottom for contact info.
I'm a software engineer with experience across multiple fields, including aerospace, full-stack web development, robotics, data visualization, and more. I've built responsive React frontends that interface with microcontrollers for real-time control, developed computer vision algorithms using ROS2/C++ for competitive robotics, and created DevOps dashboards and E-commerce features.
I also enjoy math, and I'm currently the president of SUMS (Society of Undergraduate Mathematics Students) at UCSD. I'm currently reading Douglas Hofstadter's Gödel, Escher, Bach: An Eternal Golden Braid.
