Hi there, my name is...
William (Billy) Castelli
I’m a software engineer from California who loves building full stack applications.
I am an avid fan of technology pursuing a career in software development. I graduated from the University of California, Irvine in 2020 with a degree in Computer Science. Previously, I was a software engineer at Viasat Inc. in Carlsbad, Califonia. Today, I am a software engineer at Apple in Cupertino, California.
My goal is to build technology that people find useful.
Personal projects I've built over the years
