Who? Projects Code Snippets

Raymond Hernandez, MSEM



I am an I.T. Specialist with a keen interest in both hardware and software development, and I'm particularly an expert in PHP and SQL. I earned my Bachelor of Science in Computer Engineering from California State University, Northridge, and later obtained a Master of Science in Engineering Management, specializing in Systems Engineering, from National University, San Diego.

Outside of my professional pursuits, I enjoy playing the guitar, indulging in Japanese animations, video games, collecting vintage Japanese robots, and binge-watching the Star Wars trilogy.

The projects documented here are for the purposes of peer review and education.
