 Provisioning of new technology at minimal cost, downtime and man hours, utilising
stealth rollouts and situation specific methods minimising client impact for dedicated
24/7 web hosting, file serving, filtered web and email access, constantly satisfying and
delivering Key Performance Indicators to clients.
 I have a personal focus on developing the right solution for clients, at minimal cost and
maximum longevity of project benefits.
 Effective monitoring of load and proactive allocation of resources to meet with budgets
and available resource allocations utilising effective monitoring techniques –
inexpensive and readily available. Specifically: VMWare Capacity Planner, Nimsoft,
Microsoft Performance Monitoring, MBSA, Untangle, MRTG/PRTG, Midas (Unix
based) IPSentry, and Advanced Host Monitor. These and other systems (Cisco
IPS/IDS/PIX) were also used to monitor and identify Intrusion attempts, security flaws
and areas where network resource availability/security could be compromised.
Security/Firewall
 Many companies have a strong security focus, however as a Web Publishing house
with WDG and also Racing Victoria/Spotless we had a major responsibility to protect
data sensitive clients such as Motorpass, Motorcharge, Ford Performance Vehicles,
Telstra, Australian Swimming Institute, Treasury Funds Management and many others,
to keep their information – such as credit card and client details and even swimming
event records – safe. I used both an OpenBSD Software based internal firewall and
Cisco PIX to protect Demilitarised Zones and a Cisco router with a constantly changing
rule base – defined in conjunction with client needs – to protect such important
information.
 Constant Intrusion Detection (external and internal) and Monitoring techniques were
used and security patches constantly tested and applied, following procedures
developed to protect against ‘on the fly’ changes that could compromise an efficient
security process.
 I have a Microsoft and Unix based skill set, as I recognise that no one solution should
be used to prevent unauthorised access to network resources. That said, I have
exhaustive experience in Microsoft based Security Analysis tools and other third party
Windows based applications such as Wireshark and other IP packet sniffers.
 Ability andextensiveexperiencewithvirus prevention and anti spam techniques, having
worked with and delivered Symantec, Norton, Sophos and CA Inoculan centrally
managed client/server solutions to various companies. Experience reacting to and
removing viral outbreaks and vulnerabilities.
 I have designed and implemented Certificate Services, Public Key Infrastructures,
Radius Services and VPN tunnelling techniques to provide clients with secure and
convenient access through the internet to hosted information.
 Constantly performing system hardening and vulnerability maintenance in both a Unix
and Microsoft environment through automated deployment and efficient techniques
utilising technologies such as MS Software Update Services and Windows Update
Server – Web Based MS update interfaces used to deploy updates once tested and
authorised through rigorous change management procedures.
 I have designed and implemented real-time monitoring techniques (MIDAS, MRTG,
AHM, NimSoft, IPMonitor, MS SCOM etc.) through which management can see at any

 I have carriedtheresponsibility ofhardwarecapacity decisionmakingforthepast twelve
years with Jetstar, Spotless, Thomas Duryea, Racing Victoria, Web Development
Group and Bonlac Foods. I have been responsible for developing computing
environments and labs in order to effectively simulate load and provide an accurate
indication of company hardware scope/requirements.

and implementation of MS Clustering technologies and fully redundant SAN solutions
to satisfy the ever changing needs of 24/7 Web/File/Application hosting and
development.

mounted, power/air conditioning redundant, 24/7 monitored, remotely managed Data
Facility withoffsitebackupandSAN/NAS storagecapacityestimatedtosatisfy company
demands for the next 12 months, in line with company strategies.

monitoring, fully redundant power via UPS/diesel generator, real time server monitoring
