Aerospace Engineer. Robotics Builder. Applied AI Engineer.

About Manuel Mezo

Aerospace and Mechanical Engineer (UC3M · TU Delft) with 8+ years scaling multi-million-dollar efficiencies at Amazon and McKinsey. I specialize in systems that connect software to the physical world: ROS2 robots, real-time computer vision, and deployed AI applications. My edge is rare — I understand the physics of the problem, the operational cost of getting it wrong at scale, and how to write the code that fixes it. Fluent in Spanish (native), English, and French (B2).
