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.
