What I Actually Do

From AI Chaos to a Governed Platform

Sixty seconds on who I am, the problem I keep being hired to fix, and a calculator you can drive yourself.

60-second introduction

The problem

  • Every team wires its own model calls, with its own keys and its own prompts.
  • Nobody can say what AI actually costs until the invoice lands.
  • When Legal asks why the model said something, there is no answer.
  • Swapping model providers means refactoring every service at once.

What I build instead

  • One gateway every AI call passes through, adoptable in under a day per team.
  • Spend capped and reported per team, visible before the invoice.
  • Every prompt, retrieval and answer traced and replayable for audit.
  • Changing provider becomes a configuration change, not a rewrite.
Live demo

What would governance save you?

Move the sliders. The figures recalculate as you drag.

Ungoverned $0 per month
Through the gateway $0 per month
0% saved

Illustrative only, using published list prices. Savings come from routing simple queries to smaller models, caching repeats and trimming prompt bloat — the three levers a gateway makes possible.

Milestones & Recognition

Work that shipped, teams that built it, and the moments worth keeping.

World first

The first SaaS-based 834 clearing house

EDI 834 enrolment had always run through on-premise clearing houses. We took it to SaaS — multi-tenant, HIPAA-aligned, and able to onboard a payer without shipping anyone a server.

Watch the presentation

This was where I stopped being the person writing the code and started being the person answering “why this way?” — architecture standards, impact assessments, HIPAA-aligned design decisions across a healthcare platform. The technical part I could learn. The harder shift was realising my job had become making other engineers effective rather than being the most effective engineer in the room.

Document AI.NET CoreAzure

Invoice Extraction Engine

Finance keyed thousands of supplier invoices by hand each month, with typos surfacing only at reconciliation.

Delivered a vision + LLM pipeline that reads any invoice layout, extracts line items to structured JSON and flags mismatches before posting — 92% straight-through processing.

PythonMLAngular

Adaptive Learning Platform

Every learner got the same fixed course, so strong students were bored and struggling ones quietly fell behind.

Built a recommendation engine that scores each answer, models the learner and re-sequences the next module in real time — lifting completion rates by 38%.

Event HubsService BusAzure

Real-Time IoT Telemetry Hub

Sensor data from thousands of field devices arrived in bursts that overwhelmed the legacy nightly batch job.

Architected an event-driven ingestion hub on Azure Event Hubs and Service Bus, streaming to time-series storage with live dashboards and sub-second alerting.

Azure OpenAIRAG.NET Core

Contract Risk Analyser

Legal review of vendor contracts took days per document, and risky clauses were still missed under deadline pressure.

Built an LLM analyser that compares each clause against the approved playbook, scores deviation risk and drafts redline suggestions for the lawyer to accept or reject.

Azure DevOps APIAngularPower BI

Delivery Portfolio Dashboard

Leadership had no single view of delivery health — status came from slide decks assembled by hand every fortnight.

Built a portfolio dashboard pulling live data from Azure DevOps and Git, surfacing throughput, risk and dependency clashes across six teams without anyone updating a spreadsheet.
