    I have over fifteen years experience in linux systems administration and development, having managed large environments composed of many thousands of systems. I believe I bring with me a valuable perspective on how to provide solutions for efficiently managing extremely large, and distributed environments without scaling headcount. Some of my accomplishments include having built site reliability/network operations centers from the ground up, from the development of the fault and performance management systems to the management of the staff. I have built up and administered large scale email infrastructures which would send and receive millions of emails daily. I have managed datacenter migration projects consisting of thousands of servers running live services. I have extensive experience in the online gaming industry, focusing on adminsitration, server engineering, and DevOps. I have even worked in a creative capacity as a writer and creative designer in the past, having co-created the MegaTokyo™ intellectual properties. Given the variety of roles I've had in my career, I consider myself a jack-of-all-trades. What I enjoy most is being able to provide value to the organizations that I am able to support, regardless of what role that places me in at the time.
