Hi, I'm Diego.

I'm a BS/MS mechanical engineering student concentrating in robotics. I'm most interested in the point where mechanisms, electronics, sensors, and firmware become one working system.

My work spans CAD and FEA, embedded C/C++, motor control, PCB design, fabrication, and physical testing. I'm pursuing mechatronics roles where I can contribute across mechanical hardware, system integration, and embedded control.
