Carlos Rojas
Full-stack, systems, and ML engineer. I build software, and sometimes the board it runs on.
About
High school robotics in Laredo taught me to solve hard problems with limited parts. Now I study ECE at UT Austin and build across full-stack, embedded, and machine learning.
I care about software that is clear, built to last, and honest about what it does. Most of my favorite projects sit where code meets hardware.
