After completing my MsC in Computer Science in 1997 at the Universiteit Twente, I've been consulting different customers in numerous roles and disciplines, building a broad knowledge base of IT solutions from databases, servers, networks, Server Based Computing (SBC), Virtual Desktop Infrastructure (VDI) and Enterprise Mobility Management (EMM) products.

The combination of high analytical skills, a driven personality and an eagerness to understand new concepts, techniques and products, makes me combine multiple solutions into great new Infrastructure architectures, designs and implementations.

In addition to the many assignments at customer sites and offered solutions and advice, I'm also enthousiastically sharing my knowledge and ideas through presentations at different events, like Citrix Synergy and E2EVC conferences.

My knowledge on different virtualization solutions is also reflected by the following certifications:
* RCP (RES Software Certified Professional)
* CCE-V (Citrix Certified Expert - Virtualization)
* CCP-V (Citrix Certified Professional - Virtualization)
* CCP-N (Citrix Certified Professional -Networking)
* CCA NetScaler 10
* CCA XenDesktop 5
* CCA XenApp 6
* CCA XenServer 6

In Q2 2013, I was challenged by a publisher to write a book on Citrix XenApp. For me this was a new medium to share my knowledge with the community, so I accepted the challenge with great enthusiasm. In Q1 2014 my first book, Citrix XenApp 6.5 Expert Cookbook, was published.

In Q1 2011, I received a Logica Gold Award - Employee Value Proposition "Committed" - for my professional interrelation with Logica's clients and commitment.

Specialties: * Desktop Virtualization * VDI * Server Virtualization (Citrix XenServer, VMware vSphere) * Presentation Virtualization (Citrix XenApp, RES Workspace Manager, Microsoft Remote Desktop Services) * Deployment Automation (RES Automation Manager) * Scripting (PowerShell, PHP, ASP.NET, VBScript)


Citrix XenApp 6.5 Expert Cookbook(Link)

Packt publishing
January 2014

Over 125 recipes that enable you to configure, administer, and troubleshoot a XenApp® infrastructure for effective application virtualization.

Classified as a server-based computing solution, Citrix® XenApp® offers companies a solution for Windows applications to be virtualized, centralized, and managed in the datacenter and delivered to end users from a single application portal (or store) at any time, any place, and any device. Making use of Microsoft's Remote Desktop Services, Citrix® XenApp® hosts multiple user sessions on a single Windows Server while supporting enhanced user experience through the Citrix® HDX technology that delivers bandwidth-efficient, high-quality multimedia. Combined with Citrix® Web Interface or StoreFront, users are provided with a single portal or store that unlocks the published applications and desktops. With the NetScaler Gateway, secure remote access is also supported.
By combining products such as Citrix® XenApp®, Citrix® License Server, Citrix® Web Interface or
StoreFront, NetScaler Gateway, and Microsoft's Remote Desktop Services, you can implement a full XenApp® infrastructure to deliver Windows applications and desktops to end users.
Citrix® XenApp® 6.5 Expert Cookbook will not only focus on Citrix® XenApp® as a product but will take all components of the XenApp® infrastructure into account and offer practical guidelines to install, configure, maintain, and script all parts of that infrastructure.
