About me
Freelance Cloud Architect | Altocumulus Cloud Services
My name is Wesley Geelhoed, living in Herkingen (NL). To me, enjoyment is the driving force for success. I am a very driven Freelance IT Architect with my own company Altocumulus Cloud Services. I mainly specialized myself within the multi-cloud industry for the last 10-12 years, and have a overall experience of 15 years with a focus on Networking, Security, Connectivity, and Hybrid Cloud. Before I started my freelance career I worked at VMware as a Consulting Architect within the NEMEA region.
Building virtual infrastructures and contributing to IT solutions is what I love doing most. I developed myself well on different technical areas such as private cloud, public cloud and cloud migrations focused on security and connectivity. Throughout the years I have demonstrated that creativity is core competency by presenting an developing new ideas with innovative technology and solutions. I am VMware vExpert for eight (8) years in a row and a VMware Certified Design Expert on Network Virtualization (VCDX-NV) (number 290). VCDXes are part of an elite group holding the highest level of VMware certification. A VCDX has validated its enterprise-class skills as an Architect in VMware solution design in front of a panel of veteran VCDX panel.
During each project I analyze - gather and organize information. With this information I verify from various perspectives whether a problem is actually the real problem or if is covered by the real required business outcome. I work accurately, understand structures, and make justified and sound conclusions.
I'll bring a proven track record within the VMware industry with more than 7 years of experience with the VCF suite including VCF Operations and Automation. And more than 8+ years of experience with the core products as VMware vSphere and VMware NSX
My working method can be characterized as thorough, passionate, and explorative. Finding the most appropriate solution is my drive. I am able to work successfully individually and in teams. My added value within a team are my communication skills, which help encourage other team members to develop new ideas and solutions. A challenge gives me energy!
