Less than a year later he hosted the Browser Security Sessions at the Global OWASP Summit in Portugal. He also co-founded the OWASP Builders initiative and served on the Global Conferences Committee for two years. His most recent contribution is the OWASP 1-Liner project which made him one of the few who has lead a chapter, lead a project, and hosted a global AppSec conference.
