Why me

An operator and a builder, with the numbers to prove both.

Most PMs do strategy or they build. I do both, and every claim here traces to shipped work.

AI product leadership

Four AI products shipped in production: AI-Semantic Search, AI-Intake, AI-Summarizer and workflow automation.

Commercial impact (latest)

£4M revenue, £10M in savings, a £500K repeat engagement and a £600K modernisation programme.

Builder mindset

Two AI products built solo with Claude Code, FastAPI, React and Next.js, idea to production.

Product + technical

Strategy, discovery, roadmaps and OKRs through to AI architecture, data products and GTM.

Selected work

Four case studies, outcome first.
