Darrell Owens


I'm a software developer with an active interest in housing, transit and traffic policing reform. I've contributed many software and data projects to developers, volunteer groups and nonprofit housing organizations before I graduated from the University of California, Santa Cruz in Computer Science. My work has been frequently used in news publications and academic research. This website will be an easily accessible portfolio of my products for free use.


More published maps and projects will be added soon.
