Mind Behind Harold Trujillo
Every site begins with a person, and for Computing Architectures, that person is Harold Trujillo. Growing up in Albuquerque, New Mexico, Harold wasn’t the kid glued to cartoons he was the one taking apart old PCs in the garage, curious about how every circuit connected.
That curiosity led him to study Computer Engineering at Arizona State University, where long hours in the systems lab deepened his love for problem-solving and design.
After college, Harold worked as a systems architect, building distributed platforms and helping enterprises improve performance. But even while advancing his career, he noticed something: too often, technology was explained in ways that left everyday users behind. In 2025, he launched Computing Architectures as a bridge bringing together professional expertise and plain language teaching.
For Harold, technology is not about intimidation, but empowerment. Through this blog, he shares knowledge so anyone can understand and confidently navigate the digital world.
