I'm a security engineer at Anthropic working to secure frontier AI models and products. Recently I worked on the launch of Claude Code-based security reviews, check it out here!
Previously I worked at Google focused on developing and deploying modern web security features (e.g. CSP, Trusted Types, COOP, and more) at scale across thousands of web services. Outside of work, I've responsibly disclosed vulnerabilities to over 50 different companies including Google, Microsoft, Mozilla, and GitHub. In 2020Q3 I was Microsoft's top ranked security researcher for reporting over 20 different critical vulnerabilities.
In addition, I'm active on Github as the creator and maintainer of hiSHtory with 20k+ users and over a billion synced records. I also have contributed code to a wide variety of open source projects (e.g. log4jscanner) and published many other small tools.
