D Coetzee

Former Graduate Student
Computer Science Division
University of California, Berkeley

Note: I have left Berkeley to pursue a career in consumer virtual reality. For my most recent contact information, portfolio, and resume, please see dcoetzee.com.

This page summarizes my work as a graduate student at Berkeley in online education, domain-specific embedded programming languages, and build systems.
