Selected Work

Each engagement below covers architecture, delivery and the measurable outcome for the client.

Enterprise SIEM Deployment - Microsoft Sentinel

Led end-to-end Sentinel deployments for 20+ enterprise clients in financial services, telecoms and energy: data connector integration, custom analytics rules, automation playbooks, syslog forwarding and Cisco Firepower log ingestion.

Ran POC-to-production rollouts with SOC data walkthroughs, Defender for Cloud onboarding and hands-on training for client security teams - improving threat detection visibility and reducing MTTR.

Cloud Migration Programme - On-Prem, OCI, AWS & GCP to Azure

Planned and delivered 50+ migration projects for banking, insurance, energy, government and financial services clients, covering architecture design, migration assessments, server deployment, subscription-to-subscription moves, quota management and BCDR.

Post-migration cost optimisation reduced client infrastructure costs by up to 30% while improving system availability.

Multi-Application Cloud Platform Setup

Architected and deployed Dev, UAT and Production environments on Azure for a major telecommunications provider, supporting consumer-facing applications with end-to-end provisioning, environment testing and cost analysis across all subscriptions.

Ongoing vulnerability remediation, Defender for Cloud reporting and NSG hardening produced a measurable uplift in the client's Azure Secure Score.

Azure Cost Optimisation & Consumption Reporting

Delivered recurring Azure consumption reports and cost optimisation assessments across multiple enterprise clients, identifying Reserved Instance savings, rightsizing opportunities and decommissioning actions.

Reduced monthly Azure spend by up to 25% across client portfolios.

Cost Management · Reserved Instances · Rightsizing

Azure Certification Training Delivery

Designed curricula and delivered instructor-led AZ-305, AZ-104, AZ-500 and AZ-900 courses for enterprise clients in banking, energy and financial services, including hands-on labs.

Upskilled 70+ IT professionals and strengthened client cloud capability.
