End to end Virtualisation experience from VMWare ESX/SCVMM (Microsoft) VM Build, Clustering etc. to Fibre Switch and SAN storage design, management and implementation.

Constantly worked with HP, EMC, IBM and Netapp SAN storage and replication technologies for the past 16 years.

CommVault backup solutions for large scale rollouts - companies with 50-100+ servers (Campbelltown City Council NSW, Auscript Brisbane, Servier Laboratories, Australian Education Union, City of Yarra, Nillumbik Shire Council, Mutual Trust, Orchard Funds, Korda Mentha).

Data Centre relocation to hosted Cloud solutions – NAS/SAN/Servers/Comms (Spotless, 400 physical servers).

Management and install of MS Exchange, Office Communications Server and other messaging and collaboration solutions.

Windows Server NT/2000/2003/2008 Physical and Virtual Standard Operating Environment design, implementation and administration focusing on efficient Active Directory Architecture with remote and regional considerations, in line with company strategies and specific departmental requirements.

Design and implementation of Active Directory based User Profiles and Policies developed in line with a growing web based company’s tight security focus, yet flexible young outlook on technology.

Constant development of new technologies to improve efficiency and to help meet client Service Level Agreements.

Centralised deployment of popular software applications and user requirements designed with ease of administration and rapid deployment as primary focus.

Automated SOE management/deployment with out of scope software deployment readily available pending departmental authorisation.

Adherence and exposure to ITIL Compliance and Change Management Procedures on an ongoing basis.

Experience in complete Server Consolidation Project Management, including upgrades from a Windows NT based Primary/Secondary Domain scenario across to both physical and virtual Windows 2000/2003/2008 Domain Controller based environment.

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

Proactive Monitoring and Remediation

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 and extensive experience with virus 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 time where the bandwidth is going, availability of systems or how a particular website is affecting the performance of other systems across the network.

Regular Penetration Tests using various methods to ascertain network/server vulnerabilities using methods learned in Certified Ethical Hacker training.

Hardware

I have architected and implemented various NetApp, EMC, and HP NAS/SANs, from FAS2030’s to EMC CX200/300/CX3,4,6, VMAX/VNX, Datadomain, and various SAN replication Technologies like Recoverpoint and Silverpeak appliances.

I have carried the responsibility of hardware capacity decision making for the past 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.

I have had a hands-on approach with designing physical and virtual MSCS server farms 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.

Developed the WDG network from high end, stand alone desktop PC’s into a rack mounted, power/air conditioning redundant, 24/7 monitored, remotely managed Data Facility with offsite backup and SAN/NAS storage capacity estimated to satisfy company demands for the next 12 months, in line with company strategies.

I also developed the RVL Data Centre to include redundant A/C, temperature monitoring, fully redundant power via UPS/diesel generator, real time server monitoring and SMS alerting.

I have constantly worked with and developed timely and reliable company solutions from such networking devices as hubs, switches, routers, hardware and software firewalls, web/network based printing and other peripheral devices.
