I lead infrastructure, architecture and technology decisions because I understand both board-level risk and the engineering reality beneath it. I help organisations modernise, secure and govern complex technology estates across infrastructure, cloud, cybersecurity, data and AI.

A London-based senior technology leader with nationally critical delivery behind me: more than £4M in documented cost savings, 13× platform scaling for the NHS COVID-19 response, and programmes for UK Government, the Metropolitan Police and NHS England.

01 / Profile

Who I am and
what I do

A cross-domain architect and technical leader with a foundation built through years of hands-on engineering and a proven track record of seven-figure savings on projects, spanning on-premises datacentre design and server room builds through to modern cloud platforms (AWS, Azure, OCI). Architecture decisions here carry the weight of someone who has actually done the physical work: racked the hardware, run the cabling, and designed the security layers that sit beneath it.

That combination of on-premises depth and cloud fluency is increasingly rare, and increasingly sought after. Across two decades of contracting I have also stepped into interim IT manager roles and led infrastructure teams on large-scale programmes, comfortable owning both the technical direction and the people delivering it.

Architecture practice spans infrastructure, security, cloud, data and solutions, with deep experience in hybrid cloud (AWS, Azure, OCI), Zero Trust security models, identity architecture and modern data platforms (Databricks, Snowflake, Fabric). Two years of dedicated AI upskilling covers agentic workflows, MLOps design and AI governance under ISO/IEC 42001.

Full Member of the Chartered Institute of Information Security (CIISEC) and the British Computing Society (BCS). Volunteering with CIISEC delivering assessments for membership. Working towards Chartered IT Professional (CITP) and Chartered in Cybersecurity (ChCSP).
