Subject Matter Expert (SME) with over 20 years of progressive experience architecting, transforming, and securing enterprise-scale technology environments.

I am a highly motivated IT Infrastructure Projects Lead and EUC Architect. My expertise spans cloud architecture (AWS/Azure), enterprise virtualisation, and high-scale infrastructure management. I hold a Bachelor of Engineering in Electronics and Communication and multiple premium certifications including MCSE, AWS, Azure, and Citrix.

Currently at NatWest Group Plc, I serve as a Senior Analyst — IT Infrastructure Services & Citrix, Security SME, where I orchestrate enterprise-scale cloud strategies and robust infrastructure transformations. My career is defined by leading high-performance technical teams to deliver seamless transitions from legacy on-premises environments to a modern digital workplace, integrating cloud-driven features that measurably improve business productivity.

I possess a deep technical understanding of Azure DevOps, including CI/CD pipeline automation, security policies, and Infrastructure as Code (Terraform). My philosophy bridges the gap between traditional IT infrastructure and modern global cloud deployments, ensuring reliability through Site Reliability Engineering (SRE) concepts like SLO/SLI and error budgeting. My deep EUC expertise includes comprehensive Citrix Provisioning Services (PVS) support, Citrix ADC support, and streamlining the Master Image build process using Citrix AppLayering.
