Experience
Chief Technology OfficerCurrent
Quantios · United Kingdom
Apr 2024 – Present
Quantios was formed in 2024 from the merger of TrustQuay and Viewpoint, backed by Hg Capital and EQT Partners, creating the global leader in software for the trust, corporate services and fund administration sector. I have led the technology organisation through this consolidation and the rebuild of the operating model that followed. My remit covers engineering, DevOps and production operations, cyber security as both a core technical function and a contributor to the ISMS, the Quantios Academy as the digital learning channel for our customers, and the corporate IT estate. Selected work: Leading the Quantios Agentic SDLC transformation, a redesign of how we build software grounded in the principle that agents execute and humans judge. Six mandatory human control points, governed adoption of LangChain and LangGraph with Azure OpenAI, and ADO retained for source control and CI/CD. Defined and delivered the cloud-first product strategy across the active portfolio: Core (Business Central Online), Portal, eFileConnect, and Quantios-AI and Insights. Migrating Portal from on premise to SaaS modernised our most customer-facing surface and set the template for the rest of the estate. Built Quantios AI as our applied intelligence platform, bringing generative and agentic capability into the day-to-day work of trust administration, and Quantios Insights as the analytics and data platform on Microsoft Fabric. Set the security posture for a regulated SaaS estate, including a published ISMS, a tested Ransomware Incident Response Playbook informed by tabletop and red-team exercises, a comprehensive and robust set of cyber security defences across our estate, and a fully integrated secure development lifecycle to protect our customer's data across our SaaS portfolio. Structured the architecture function, forming the Portfolio Architecture Team, and establishing the Architecture Review Board governance.
