As the Principal Virtualization Engineer I served as a subject matter expert and provided an authoritative level of solution design, consultation and implementation on a variety of Microsoft, Citrix and VMware Virtualization Technologies. I was responsible for the successful delivery of strategic and technical projects in all levels of complexity. With a broad range of business experiences and knowledge I worked to improve the business and IT alignment for our clients, set project scope, service pricing and scheduling of other consultants for projects related to these technologies.
Throughout my career I have consulted and implemented Microsoft and Citrix & VMWare technologies on every engagement. My demonstrated deliveries and consultative services have achieved top rankings from our clients. I also provided technology review sessions and am a host speaker to our customers where I provide an in-depth technical presentation of new products, services and best practices. I also mentored our staff engineers from a technical level and provided an escalated level of support where needed.
I provided leading edge concept and design sessions with internal staff and clients to resolve unique business challenges where reduction of cost and rapid implementation is the key for success.
Provided various on site and remote levels of project and technical leadership. Utilized my broad skill set to implement and troubleshoot server and client operating systems, LAN / WAN and Wireless environments.
Consistently received letters and emails from clients complementing service and workmanship for myself and assigned consultants. I also precipitated in pre-sales consultations and assisted in closing deals through demonstration of Citrix and VMWare & Microsoft.
I have been very successful in providing my clients a tailored approach to implementation of Microsoft and Citrix & VMWare technologies through a series of consultative interviews with each client.
