Software engineer based in Australia and South East Asia.

Over many years of experience in a variety of environments I have developed a broad range of skills and have designed & delivered numerous high quality software projects.

I have much experience in training and mentoring, being able to explain technical topics clearly. I enjoy the “craft” of software development and am interested in helping others get the same satisfaction.

My publicly available source code is available at https://src.userspace.com.au and some things mirrored at GitHub and/or GitLab.
