Curriculum Vitæ

Kevin Collas-Arundell

Summary

Linux Ops person. Does Go, Kubernetes, LANs and runs slowly. I’ve been in devopsy roles for more than 7 years with a significant focus on close coordination with development teams. In my roles I have had to frequently and continually communicate across teams to reach success. What started as identifying and solving requirements for other teams at RMIT lead to working directly with Development teams to build new systems at Hitwise and Aconex and being one of the developers at LIFX. Over the last 3 years my software engineering skills have had rapid growth as I moved into a role that was effectively split between development and operations responsibilities.
