I am a Linux and Unix specialist who believes strongly in all protocols and interchange formats being openly and publicly documented. I operate full-stack, developing code
from the front-end through to the bare silicon with a focus on the lower parts of the stack.
I am passionate about keeping e-waste down and reducing energy footprints for the sake of preserving our environment. As a non-driver, I work exclusively in the Brisbane area, with a requirement for workplaces practically reachable by public transport, bicycle or on foot (from The Gap).
