Business continuity concept and geo-redundant high availability design

Review and approval authority over all low-level designs, application and infrastructure: network security, Oracle RAC, VMware, OpenShift, SQL clustering, geo-redundancy

Designed and implemented full hardware and network separation between test environments and staging/production

SME for third-party security audits against CIS benchmarks and NIST standards: preparation, execution, findings analysis, remediation prioritisation

Delivered software deployment to 45,000 retail terminals with minimal downtime, plus data migration from the incumbent end-to-end landscape to the new architecture

Transitioned 45,000 POS terminals and 19 million online players on time with no critical incidents

Owned the integrated transition plan for the full replacement of the lottery technology stack: work packages, milestones, dependencies and critical path across parallel technical sub-projects

Central organisational interface between internal IT leads, technical workstream leads, multiple external vendors and client executive stakeholders

Planned and led migration and cutover of live, regulated national infrastructure, including 80+ bare metal servers running VMware ESX, Microsoft VMs across several Active Directory domains, Linux VMs, OpenShift on Linux, 2 SANs, 2 Oracle Exadata systems, AWS components and a retailer WAN
