Dennis Cao, Full-Stack Software Engineer & Electronic Musician

📍 Currently based in Los Angeles, CA.
🎓 UCLA B.S. Electrical Engineering / Digital Signal Processing.

I've also worked as a music producer, on an Oscar shortlisted animation - PengLai and making electronic music under the alias Dian Nao Xin. When I'm not working on my computer ... I'm most likely still at my desk learning new things, working on personal software & hardware projects, or making music. I also enjoy cooking and hanging out with my cat, Chi Chi (there she is on the right).
