I can recommend Eef for being an extremely versatile and knowledgeable project- and interim line manager, after having worked with Eef in four different instances and three different companies.
Eef knows to adapt seamlessly and pleasantly to the environment, whatever the circumstances, be it in a line-management or project role. The cases in which I have seen him operate were of a very different nature, but always including the implementation of IT at the interface with a challenging technology environment, involving many stakeholders. Eef performs well in that context since he also oversees the non-IT related aspects, both technical and man-management related, and comes with pragmatic solutions. Eef manages to quickly separate the wood from the trees, setting up an efficient way of working whilst carrying the team with him. He stands out for delivering as promised and transparency towards stakeholders. He combines this management approach with a broad knowledge of the IT environment and a stamina to always look for the solution to the next problem. Being a very honest, modest, loyal and constructive person, he earns respect and leadership by own delivery and ability to energise others to the same high standards.
