I work closely with high profile clients to assist them with migrating their web applications into the IBM Cloud. Application and security requirements vary greatly from customer to customer. I consult with customers to understand all of their requirements. I then architect and implement their cloud migration. Migration/integrations required interactions with sales and project managers.
Senior Systems Administrator

I manage/maintain over 100 CentOS 6 servers within Amazon’s cloud to keep petfinder.com up and running. On a daily basis I use (and constantly tweak) tools like Nagios, Splunk, Puppet, and Bash scripts to help me keep the system up and running. In 2013 I single-handedly migrated all of Petfinder’s systems out of a physical data center (Equinix) into Amazon’s cloud (AWS).
