About
Most of my career as a tech professional has been as a sysadmin doing desktop support, then managing web and application servers, and finally, integrating applications in a global corporate environment. For around a decade in the middle of all that I served as lead engineer for directory and identity access services with the same company.
As more software solutions have moved off-premesis to the cloud, I've been spending a lot of time working with the new technologies that are being made possible by application containers, software defined networking and serverless architectures.
