THE
£150K → £3.5M
PROBLEM.
The interesting part wasn't the storefront. It was the machinery underneath: multi-channel inventory reconciliation, ERP integration, automated marketplace repricing, and logistics workflows.
Operating across specialist omnichannel retail & manufacturing operations, we scaled online sales from ~£5,000 to £80,000 per month, contributing to group revenue growth from ~£150,000 to £3.5 million over three years across 12 channels and high daily order volume.

02.5 / IMPACT & REPUTATION
What executive peers and commercial leaders say.
“Ciaran took an operation drowning in manual spreadsheets and fragmented channels and turned it into an automated machine that handled 1,000+ orders a day seamlessly. He understands the commercial P&L just as deeply as the technical stack.”Managing Director Specialist Retail & Logistics Group
“Ciaran has the rare ability to sit with developers to design idempotent API integrations in the morning, and sit with directors in the afternoon explaining how the architecture drives margin and operational resilience.”Head of Digital Operations Multi-Channel Commercial Systems

04 / THE WAY I THINK
Most “technology problems” are business problems wearing technical clothes.
01TURN CHAOS
TURN CHAOS
INTO SYSTEMS.
When a business has fifteen tools that weren't designed to work together, I work out what the architecture should actually be.
02MAKE DIGITAL
MAKE DIGITAL
COMMERCE SCALE.
Commerce platforms, marketplaces, product data, fulfilment, payments and automation — treated as one cohesive operating system.
03BRIDGE TECH
BRIDGE TECH
+ COMMERCIAL.
I can sit with developers about APIs and with directors about margin and P&L. The superpower is joining those conversations together.
04USE AI WHERE
USE AI WHERE
IT ACTUALLY HELPS.
Agents, MCP, and automation are valuable when they remove operational friction or create leverage — not to check an AI marketing box.

The T-shaped Technologist: Hands-on depth, boardroom perspective.
I CAN SIT WITH
DEVELOPERS,
COMMERCIAL TEAMS
AND DIRECTORS.
I've spent 18+ years writing production software, which means I understand how systems fail under load. And I've spent enough years running commercial operations to know that engineering elegance is useless if the economics don't work.
I partner with founders, CEOs, and engineering teams to turn fragmented technology into reliable, scalable commercial infrastructure.

We Didn't Need More Traffic. We Needed a Better System.

AI Is Changing the Landscape. But Probably Not in the Way You Think.
When the cost of writing code drops toward zero, the constraint shifts from "Can we build it?" to "Should we build it?" and architecture becomes more critical than ever.
