> Making data a controlled substance

Location: San Francisco, California, United States
Profile: https://flows.cv/calebholtzinger

While I recognize the value that data collection can bring to improving a user experience, I also believe that privacy is a fundamental individual right. I'm interested in working on projects that sit at the intersection of these two principles: designing systems that are effective to the products they power as well as respectful of user autonomy. 

Besides this, I ride bikes and make music. If you're a recruiter, please mention this when you reach out.
