To take up a contract that will benefit highly from the full range of my infrastructure and application development and deployment skills, and allow me to remain at the leading edge of information technology


Coming from a background of being a top Microsoft systems guru with 20 years of unparalleled and intimate experience across the full stack of technologies in a large scale mission critical enterprise setting, from understanding how it all works under-the-hood and low-level implementation to being able to architect, design, plan for and deploy multi-thousand user systems, I am super capable of transferring my existing knowledge to new or expanded problem spaces in both architecture and software development

I have designed and built from the ground up systems based on the TCP/IP stack (DNS/DHCP/WINS down to packet level), authentication and directory services (AD/LDAP/PKI/Radius/802.1x), client management (SCCM/MSI/GPOs), highly available/geo-clustered Exchange (from 5.5 to 2016 and Office 365 including low level programmatic mailbox and public folder database access and ADFS), multi-node AlwaysOn SQL, Microsoft identity Manager/FIM with business rules logic development in C# (compiled to a DLL), as well as the underlying networking, storage and security technologies (Ethernet and GRE packet-encapsulation/software defined LAN, Frame Relay, leased line/dark fibre, MPLS, VPN and Satellite WAN, static and dynamic VRF routing, network load balancing (F5), fully redundant entry/mid and high end Fibre Channel, iSCSI, NFS, FCoE and software defined SAN/storage, centrally managed anti-virus/anti-malware and network-to-application-layer firewalls, SIEM, IPS and IDS) – at times exceeding vendor specifications for maximum achievable performance and precision

Further expanding my scope to open source technologies, I have also mastered high security Red Hat Linux/Satellite deployment and clustered Oracle and DB, and later Puppet and AWS/Azure infrastructure-as-code scalable networking, IaaS, PaaS and SaaS technologies in a DevOps Agile/CI/CD/test-driven-development setting, coding production use applications in C#, and making forays into a full range of open source technologies – RESTful APIs, PostGre SQL, MuleSoft ESB, NGINX WAF/load balancer, Red Hat OpenShift, Docker/Kubernetes, Kafka, Chef/Ansible, AWS Aurora/RDS/ElastiCache, Jira/Confluence/Bamboo, JSON, Git, Python scripting, Angular.JS and HTML5 for web front-end, Node.JS for server, as well as multi/3 tier application architecture and MVC and C++

I have managed my own and vendor outsourced projects in environments from 250 staff in Asia Pacific region to 75000 staff strong European Commission, acting as a (team) lead consultant, engineer, designer/architect – to vendor design assurance for a 2-billion-dollar new hospital opening project with a 200 million $ ICT budget at Queensland Health in Australia.

Having worked with some of ICT industry’s veterans and best brains who have written code that still forms the basis of MS Windows OS and participated in architectural framework definition, I have learned business (process) analysis and engineering, functional and non-functional requirements gathering, TOGAF and IT4IT architecture governance, information architecture with ontology/taxonomy creation, and enterprise architecture to the point of being able to inform and lead bespoke software design, create and interpret UML diagrams and user stories, and design and code the specific solutions, as well as define an end-to-end computing and security strategic vision for a 3-5 year horizon

ITILv3 and Prince2 Practitioner certified, able to lead, support and manage and influence and act as a trusted business advisor, I possess a deep and broad experience in project and portfolio management and consulting to business stakeholders up to C-level

Following on from my original partnership with EC DG Relex (European Union External Relations department precursor to the new Foreign Service) in 2004-2007, as a trusted advisor and an authoritative source on matters of enterprise infrastructure services, I was asked to re-join the organisation during their second key period of becoming a new institution with own IT services, owning the portfolio comprised of the Identity Management, Directory Services and Messaging platforms, all being spun off into a new independent service. I:

·        Led the solution architecture I previously helped establish at the organisation through delivery of a comprehensive Enterprise Technology Roadmap and evolution discussions for the future technology selection and adoption according to business strategic requirements
