For the past couple of years I have been working mostly in cloud-computing, both with government funded non-profits and as an independent consultant. My consulting work consists mostly of helping companies build their apps to be cloud ready, as well as migrating apps into cloud based services, and managing those apps once they are deployed to the cloud. I have lots of experience with AWS and RackSpace and other OpenStack clouds. Much of my work last year was actually implementing and maintaining cloud provider infrastructure based on OpenStack for various government projects. That experience led me to build my own public cloud based on OpenStack with a storage back end based on a ceph cluster for instance, object and volume storage which I am beginning to sell to my consulting clients in addition to other services I provide for them. Prior to my cloud experience I worked as an IT Director and Senior Systems Admin in conventional IT shops and have plenty of experience in datacenter operations, VMWare based virtualization, switching and routing, full ISP operations including large scale deployments in VoIP based on open source technologies. I would love to have an opportunity to meet with you and discuss how we may be able to work together.
