Currently working as a Sr. Software Engineer specializing in building solutions using the entire Microsoft .Net suite of products (Visual Studio 2008/2010, .Net 3.5/4.0, Asp.Net, C#). All of my application solutions are built around performance, efficiency, and simplicity...so long as the business requirements allow them :-)
I also have experience with identity and access management systems like Shibboleth which is a Java-based open-source SSO software. Shibboleth environment was setup on a Linux platform with Apache web server and Tomcat. I wrote a special membership provider to integrate Shibboleth SSO with Sharepoint 2007.
In a past job, I was a Tibco Administrator specializing in building Tibco SOA architecture.
