"Headspring Systems asked SysVision [my previous company] to take over the management and hosting of an OpenCMS web site from another vendor and Mathias served as point of contact for SysVision working hand and glove with Headspring, the other party being relieved of ownership, and Headspring's client to whom the web site belonged. Mathias proved very knowledgeable and a quite capable in managing a migration. I recommend Mathias Lin. I know anyone who uses his services is in good hands." - July 27, 2009
