I’m a security researcher and application security engineer focused on vulnerability research, web security, and building tools to make application security easier. I founded the OWASP Indianapolis Chapter in 2005 and curate appsec.fyi, a collection of application security resources.

I’ve worked at Microsoft, Proofpoint, Salesforce, Teradata, and Anthem, and I’ve spoken at DerbyCon and CircleCityCon on topics like extending Burp Suite and Ruby security.
