Work Experience

Dimensiondata (Formerly Opsource Inc.)

Ashburn, VA October 2005 to present

My position at Dimensiondata (Opsource) has evolved considerably since I started.

I started as a Systems Engineer I have been responsible for the day today care of multiple client environments. Opsource is a software as a service company and our clients have segregated networks within our shared infrastructure. I have supported mixed Windows/Linux (mainly Windows) environments that were focused on delivering applications to web users. I have been the lead engineer on several consolidation and upgrade projects during my time at Opsource. One project consolidated systems that we had spread out over 3 datacenters into our primary datacenter using VMware.

Over the years I evolved into our Cloud Business Units Virtualization architect. This started to change in 2008, when I became a dedicated Virtualization Engineer and was put in charge of our Managed hosting VMware platforms. This platform started off with 8 Dual CPU hosts and 32GB Ram in 1 datacenter Running ESX 3.5.1. I was responsible for setting the VM standard configurations, creating templates, provisioning customer VMs, troubleshooting any issues and maintaining the environment and upgrades. This experience helped me learn PowerCLI, I used that to automate the deployment of new VMs and to create capacity reports that were used to justify new capacity adds and determine what configurations out data centers could support.

In 2009 I helped design and implement our first step into the Cloud Service provider business. I worked as part of a team with Network engineers and Developers. I helped layout the ground work for the Opsource Cloud infrastructure. This launched to the public in Oct 2009, I continued to manage, maintain both the Managed hosting platforms and the Cloud Platforms. As the Cloud business continued to expand I was made a Team lead and was responsible for hiring new engineers that directly reported to me. We were responsible for all the support and maintenance of the platform, support of the customers and helping develop new features.

Dimension Data Purchased Opsource in 2011 and formed the Cloud Business Unit

In 2014 I had a team of 8 engineers supporting 25 datacenters around the world. We had approximately 300 Esx hosts and 25,000 VMs under management/support. To help us continue to expand the team was split into 2 groups, Operations and Product Engineering. I stayed with the product engineering group and was able to keep a team of 3.

As the Product Engineering Virtualization team lead, I am responsible for new upgrades and products related to Virtualization (VMware specifically) We create the testing Parameters, Designs and implementation documentation for all new upgrades, products and features we create for our Cloud Platform product.

Pace Systems

Naperville, IL September 2004 to October 2005

As the Senior Systems Engineer I am currently responsible for all the internal IT operations as well as the planning, management and implementation of all client related project. Internally I have been given the task of standardizing all of our in-house and client documentation.

I have also planned and implemented upgrades from Windows 2000 to Windows 2003 AD upgrades for both our own internal needs and external client requirements.

Currently my focus is on Citrix Metaframe Presentation server. This is the primary platform for most of my clients as well as our internal environment. The ease of use and rapid ability to deploy applications to a large number of users is very appealing to most of our clients.
