Technical Consultant

I turn unstable systems into scalable, well-governed platforms.

I work with founders, engineering leaders, and enterprise teams who need senior technical direction, platform architecture, and systems that scale without the cost or latency blowing out.

Open to contract, fractional, and full-time opportunities

About

I've been writing PHP since 2006, and building on WordPress since 2007. I started out in IT management, moved into development in 2011, then ran my own company for a few years before a good enough opportunity brought me back into full-time employment.

I've built for individuals and charities, government departments and multinational corporations, and most sizes of client in between. My work's spanned CMS and LMS platforms, AWS and Cloudflare infrastructure, Node.js and JavaScript development, and more recently AI — folding LLM and agentic tooling into the same production discipline as everything else I build, not treating it as a separate demo.

Core Specialisms

Platform Architecture

Challenge

Unstable systems and legacy code

Deliverable

Scalable blueprints, cloud migrations, decoupled systems

Fractional Leadership

Challenge

Teams needing senior technical direction

Deliverable

Engineering roadmaps, hiring support, sprint governance

Performance & Scale

Challenge

High latency and escalating server costs

Deliverable

Database optimisation, edge caching, load resilience

AI Integration

Challenge

AI tooling that stays a demo, not a working part of the system

Deliverable

RAG pipelines, agentic workflows, and LLM integration built into production systems
