Enterprise-Grade IT Strategy
Strategic Infrastructure Leader and MBCS-accredited professional with over 8 years of experience architecting resilient multi-cloud environments.
Henry Poppelwell, MBCS
Principal Infrastructure Consultant
I specialize in driving cloud maturity through "Security by Design" frameworks and advanced PowerShell automation to eliminate operational overhead.
My background is rooted in the high-stakes world of enterprise IT. During my tenure at Accenture, I delivered critical technical projects for major institutions including the NHS and Dyson. Later, as Lead Systems Administrator for Cintra HR and Payroll Services, I architected and prototyped a high-availability AWS cloud infrastructure for a new flagship payroll product, ensuring 99.9% uptime during peak processing cycles. Alongside this cloud adoption, I spearheaded company-wide initiatives to achieve ISO27001 and Cyber Essentials Plus certifications, securing highly sensitive financial environments.
I have a proven track record of delivering high-stakes projects, including complex tenant migrations, always maintaining a strict focus on governance and measurable infrastructure ROI.
