About

I'm Justin Cruz — a Cloud Computing graduate and U.S. Air Force veteran with a passion for tinkering, automation, and continuous learning. My work spans server maintenance, scripting, and cloud technologies, where I thrive at the intersection of hands-on engineering and scalable infrastructure.

I enjoy solving complex problems, experimenting with homelab setups, and constantly expanding my skills in cloud platforms like AWS and Azure. Whether it's optimizing GPU clusters or teaching others what I’ve learned, I’m always looking for ways to build, break, and improve.
