I am Jérôme LELEU and I founded CAS in the cloud in 2014.

I am available remotely for expert missions on CAS, pac4j, OAuth, OpenID Connect, SAML
or more generally on authentication, application security, SSO or IAM.

Contact me at jerome@casinthecloud.com

CAS is the SSO solution used by plenty of universities and companies all around the world.

As a committer (the main one in Europe) of the CAS Open Source project, I'm one of its major contributors and I know very well its features and capabilities.

I talked about CAS at Devoxx France and for 8 years at the SFR telecom company, I have been in charge of one of the biggest CAS installations in the world (millions of users and logins each day).

I now work on CAS authentication projects for my clients.

It's the security framework to use in Java. It is available for multiple environments (J2E, Spring, Play, Shiro, Vertx and etc.) and handles many authentication mechanisms (like CAS, basic auth, SAML, OpenID Connect, LDAP and JWT).

As the creator and leader of the pac4j Open Source project, I perfectly master this software. I presented pac4j at the Paris JUG.

I often support clients to integrate their applications with pac4j in the best way or add new features.

I can also bring my expertise on the OAuth, OpenID Connect and SAML protocols, their related tools and the security libraries.

More generally, I can advise you about authentication, security, SSO, and IAM with best practices and audit.

Lastly, I sometimes help my customers with architecture design, performance audit, and multi-technologies development.

If you are looking for a project manager, a scrum master or an agile coach in Bordeaux,

my wife Sophie LELEU , PMI-ACP certified, is the person you need.
