Notable Projects & Achievements
ISO 27001 & 9001 Compliance Program
As Deputy ISO Manager at Addooco IT LTD, established and maintained ISO 27001 and ISO 9001 certifications — unlocking enterprise and public sector contracts that would otherwise have been off limits to the business. Developed the documentation, controls and quality processes; led internal audits and coordinated external assessments to keep both accreditations live year-on-year.
Hyper-Converged Infrastructure Deployments
Led multi-site hyper-converged infrastructure projects consolidating legacy estates into modern virtualised environments. Reduced operational overhead and hardware footprint while improving resilience and DR capability — migrations completed with minimal downtime on business critical workloads, protecting client revenue throughout transition.
24/7 Courier Operations Automation
At Courier Logistics Ltd, automated the daily depot and hub processes underpinning a nationwide 24/7/365 courier operation serving 2,000+ customer accounts. Eliminated manual overnight intervention, removed a single point of failure and kept the business trading through every peak season without operational downtime.
Enterprise Solutions Architecture
Designed and delivered enterprise solutions at Sheffield Business Systems spanning Exchange, Windows Server and virtualisation platforms.
