Sander Van Der Waal is a Research Director at Waag. They possess expertise in open source, software development, java, architecture, software engineering and 13 more skills. They is proficient in French and German. Colleagues describe them as "Sander is a hard working, loyal, enthusiastic person who has been a pleasure to work with. He is extremely professional and diligent, and demonstrated initiative, and an ability to work at all levels (from academics to senior government representatives). He has extensive contacts across Europe and beyond, and is regarded as a key player in his field." and "Working with Sander continues to be a pleasure. He is one of those people who will accept a task and just get on with it. Often the next you will hear from him is delivery, on time and to an exceptional standard. Occasionally there will be a request for clarification on important and often subtle points that will usually challenge and stretch you (but usually only a single clarifications meeting, no continual interuptions here). He's not afraid to ask for guidance and is equally willing to offer it both upwards and sideways within the organisation. I can honestly say I have learned a great deal from Sander, and look forward to continuing to do so. As an ambassador of the organisation he is an asset. He engages well with third parties, identifying opportunities for collaboration and either acting on them, when within remit, or passing on the lead to an appropriate colleague. All I ask is that you don't hire him away from me."
