Profile

Lead Architect at Thames Water, owning AI and architecture governance across a regulated enterprise estate. I built the AI governance capability from scratch: use-case classification, risk-tiered controls, an AI register, and review gates that sit inside delivery rather than alongside it. The architecture work covers the programmes nobody volunteers for: end-of-life content platforms, bespoke system retirement, and document migrations counted in millions.

Background covers UK utilities, defence, and vendor-side consulting at an architecture tooling firm. Most of the job is the unglamorous part: getting decisions written down and owned before delivery makes them by default.


Core capabilities


Experience

Lead Architect (Solutions & AI)

Thames Water · Reading, UK (hybrid)

  • Lead one of two solution architecture teams, reporting to the Head of Platforms and Solutions Architecture. Permanent architects report to me and oversee contract architects across programme delivery.
  • Own AI and overall architecture governance across the estate (cyber security sits with my peer Lead). Every AI use case passes through risk classification, tiered controls, an AI register, and defined review gates before build.
  • Maturing the governance function toward a standalone, delegated capability with its own decision rights.
  • Lead architecture on ECM modernisation: replacing end-of-life document platforms and migrating millions of documents out of ageing systems while live operations continue.
  • Architect the replacement of critical bespoke line-of-business systems, currently a legacy estate moving onto Salesforce.
