Introduction
I am a technologist with a lifetime love of computers and technology. I have experience with an extremely wide range of programming languages, operating systems, and technical positions. I bring a personable and professional attitude that enables me to motivate and lead teams of professionals in fast paced and highly technical environments. In my career thus far, I have experienced two company acquisitions and created Kuberhealthy, which has become widely used and was adopted by the CNCF in April 2021. In my recreational time I enjoy archery, firearms, sport driving, and of course PC gaming.
