Intrabreeze
Between 2004 and 2011, I worked at Vocollect as the in-house intranet manager. And so during that time, I had the opportunity to design and develop my own intranet and content management system in PHP and MySQL. Authentication tied in to Active Directory, and features included message boards, events, employee profiles, page hierarchies, HR forms, events & education registrations, featured employees, and much more. It was such a complete product I had considered reselling it to other companies under the name Intrabreeze.
