About Me

Technology Leader Who Delivers from the Inside

A hands-on CTO with 20+ years across technology, from early career web development and digital marketing, through 9 years leading engineering and digital strategy, to 4 years as CTO. I take ownership of the technology function and leave it in better shape than I found it.

My Approach

I bridge the gap between technical possibility and business reality. AI has fundamentally changed how software gets built - I orchestrate AI-augmented engineering workflows to ship faster, with fewer people, and at higher quality than traditional teams.

After two decades of watching technology hype cycles come and go (cloud, mobile, social, blockchain) I know what separates real transformation from expensive experiments. AI is not the next hype cycle - it is the new baseline. The question is not whether to adopt it, but how effectively your organisation wields it.

When a platform needs re-architecting or a system needs rebuilding, I lead the delivery end-to-end, from architecture through AI-assisted implementation to production. That combination of strategic leadership and hands-on delivery has defined every role I have held.

Full Ownership

I take the CTO seat with full accountability: team, architecture, security, roadmap, and board reporting. No half measures.

AI-Augmented Delivery

AI is the new baseline, not a differentiator. I embed AI across the entire engineering lifecycle, from architecture to code review, to ship faster and leaner.

Operational Excellence

Efficient processes matter as much as clean architecture. Lean thinking meets technical precision across enterprise SaaS, integration middleware, and cloud infrastructure.

Business Fluency

I present to boards and align technology investment with commercial outcomes. The CTO role is a business role first.

Career Journey

7 years in web development and digital marketing, 9 years leading engineering and digital strategy for enterprise clients, then dual CTO roles spanning SaaS and data-intensive platforms.
