Robotics engineer. I build the hardware, code, protocols, and control interfaces that let people interact with robots, and I am working toward robots with character. PhD in Computer Science (UPV, 2025), BSc in Robotics Engineering (PUC Chile).
I own products end to end, down to the name on the box. My prototypes are printed, soldered, and wired at my own desk. At Crystal Lagoons I built the controller and digital twin for a cart that cleans lagoons, and the first time it stopped exactly where I clicked is still my favourite moment in this job. At Lucid Bots I wrote the library that lets the app talk to the robot. Since 2026 I build Auri Labs.
A robot is not finished until a person can use it.
