Operator-engineer. I run a small UK services group day-to-day and design, ship and own the LLM and automation systems it depends on — RAG knowledge platforms, decision co-pilots, and an integration backbone where nearly half of all activity is now automated. Self-taught by shipping things a real business depends on every day.
An organisation-wide retrieval system that turns scattered business knowledge into grounded, cited answers. Postgres + pgvector with hybrid (vector + keyword) retrieval and reranking; auto-capture; an automated eval harness and a human-in-the-loop critic gating what gets trusted.
Task-specific co-pilots in daily use by leadership: a seasonal cashflow forecaster, an operations risk co-pilot that flags job risk from combined operational, weather and routing data, and marketing-attribution dashboards. Built on pure, unit-tested TypeScript libraries.
A central pricing engine as a single source of truth, powering AI-assisted instant quoting and a self-service booking journey that integrates CRM and e-signature. Moved the business toward fewer, higher-value jobs.
An idempotent, rate-limit-aware integration layer connecting CRM, field-service, finance and e-sign. Replaced a fragmented, multi-system manual process with automated gate-based tracking and a single live control panel — removing manual data entry and month-end reconciliation.
Migrated multiple brand sites to Astro + Cloudflare with zero loss of search rankings, consent-gated analytics and CRM lead capture; ran technical SEO and Core Web Vitals programmes that grew organic demand while cutting acquisition cost.
LLM features ship against golden-set evals, regression checks on prompt/model changes, and citation-grounding gates — so reliability is measured, not assumed.
I start from the business outcome and work back to the system. Every build has a number it's meant to move — and I own whether it moved.
I take businesses from owner-dependent to system-led: documented processes, automation and dashboards so things run without depending on any one person.
