Free Strategy Call
45 minutes on your business, your workflows, and where AI fits. I'll be direct about what's worth doing and what isn't.
Practical AI. Built Right.
I've spent a decade building AI products — as a startup CTO, as an architect for a Fortune 100, and as the person writing the code. Now I do the same for businesses that want to move fast without cutting corners.
AWS AI Hero since 2018. You work with me directly.
How I Work
From startups to established teams. I build working software quickly — days or weeks, not months.
02Fixed Cost
Pilot
Fixed-Price Prototype
I build a working pilot scoped to one real problem. You see it work before committing to anything bigger.
03Scoped Project
Build
Production System
From pilot to production. Proper architecture, your data handled safely, integrated with your existing systems.
04Monthly Retainer
Partner
Technical Partner
Ongoing AI leadership for your business — strategy, architecture decisions, and hands-on building. A CTO-level partner without the full-time overhead.
Solutions I Offer
The right tool for the job.

Using ChatGPT Teams, Microsoft Copilot, Claude or Gemini? I can help you optimise your existing tools for your business.
I need to validate my ai idea
Pilot Sprint
Research your AI idea and validate it with a working pilot—like my deep research lead-gen agent.
I need to find information faster
Intelligent Search
Turn scattered documents into a searchable knowledge base with cited answers.
I need to automate repetitive work
Automation & Agents
From simple integrations to autonomous agents — I help you find the right level of automation.
I need to process documents & calls
Conversational AI
Transcription, summarisation, extraction — turn unstructured content into structured data.
I need to own my ai completely
Custom Models & Hosting
From on-device models to fully managed hosting. I help you choose the right infrastructure, even if you don't have a tech team.
I need to get ongoing guidance
Fractional AI Advisor
A trusted expert on retainer. Strategic guidance, vendor evaluation, team upskilling — without a full-time hire.
Honest advice included: Sometimes the answer is a sophisticated AI agent. Sometimes it's a better spreadsheet. I'll tell you which one and why.
Fast to pilot. Safe to scale.
Built Right
I built a SaaS AI platform as CTO of a startup inside a Fortune 100 insurer. I know what "move fast" looks like, and I know what regulated means. I size the engineering to fit.
Security That Fits
Enterprise-grade when you need it. Lighter when you don't. I won't over-engineer your startup or under-engineer your compliance.
Your Data, Clear Rules
I'll walk you through residency, retention, and privacy choices in plain language. You'll know exactly what applies to you.
Audit Trails When Needed
Full traceability if your sector demands it. Sensible logging if it doesn't.
You Own What I Build
Your code, your infrastructure. I'll be upfront about any third-party dependencies or licensing.
The Name
Why Chatitecture?
Chat is everywhere — messages, documents, voice notes, emails. The messy, unstructured information that runs most businesses. Until recently, software couldn't do much with it.
Architecture is how you turn that into something useful. Not a demo. A system that integrates with your business and handles your data properly.
Chat + Architecture = Chatitecture
Human language + Software engineering = Working product
Led by Experience
Gillian McCann
Founder & Lead Architect
I've been building AI products for over a decade — digital assistants, search systems, conversational interfaces. As a startup CTO, as a cloud architect for Liberty Mutual, and as the person writing the code. I know what it takes to ship, and I know when to keep things simple.
