I worked with project server since project server 2003. Most of time, I am focus on project server customization and development. I am very familiar with project server database schema, object model and web service.
I also have very good experience on SharePoint development and .NET application development.
Right now, I am with Catapult Systems (http://www.catapultsystems.com), which is Microsoft Gold Partner. Before that, I worked with The ProjectGroup , which is also Microsoft Gold Partner.
