About Jérôme

I provide expertise / consulting / implementation services on CAS and pac4j, but also on OAuth, OpenID Connect, SAML protocols and more generally on authentication, application security, SSO and IAM.

I live near Bordeaux and work mainly remotely. I also travel on-site occasionally for my clients.

I have 19 years of experience and am one of the biggest contributors to the Open Source CAS project and creator of the pac4j security framework.
