Mass surveillance on the internet is a major global issue. The human right to privacy has never been more continuously violated than it is today. To preserve freedom and democracy, we need to make sure that everyone's privacy remains protected.Since 2014, I have been working on addressing the issue of internet privacy by working to make web browsers more private. I have worked on privacy teams at the Tor Project, Mozilla, and (now) Brave, adding new privacy protections to web browsers. In addition, I created and maintain PrivacyTests.org, an open-source project that regularly audits web browsers for their privacy leaks and makes the results public.
