Major Skills
- Extensive Linux (many distributions) and Solaris Systems Administration experience in complex, 24/7 environments.

+61 7 3236 0262
Position: Consultant, reporting to Company Director.
Key work includes:
- Reimplementation and ongoing maintenance (especially trouble-shooting) of the gateway environment for a large manufacturing and services organisation. The environment hosted the company's' websites and email, remote access to key corporate systems, business-to-business systems and provided access for many desktop users at numerous sites.
- Extensive debugging and troubleshooting of environments that only ever seem to grow more complex as time progresses.
- Technical security audit of systems and related work on "secure build" documents for both government and financial organisations.
- Development of quality, maintainable "glue" scripts to connect various systems together in ways not properly support by the systems themselves, for example, importing data into a large management system.
- Administration of Solaris hosts in a gateway environment; designing, implementing and maintaining a set of daemons to enforce security policies on those hosts; and creating a system of scripts to trace graph email from though the entire security gateway complex.
- Introducing major improvements to a reporting system on Internet access for a 60,000+ user population. This included tools to generate reports (daily and on-demand) and a web interface allowing arbitrary searches across many gigabytes of Internet access log files.
- Mentoring several colleagues in secure programming techniques, mainly in Perl and Shell on Solaris and Debian GNU/Linux systems.
- Integration of commercial anti-virus software into both email and web filtering for a large client using free and open source software before it was the norm.

During my four years as a student at The University of Queensland prior to starting full time work in 1998, I undertook many computer support roles. These included desktop support and Systems Administration for Computer Science and Electrical Engineering faculty members.
