About

Enterprise experience. Small business prices.

I’ve spent 25 years creating automated solutions across multiple operating systems, services and processes for financial institutions and major technology vendors. That same engineering discipline now goes into every project, whether it’s a website for a local café, a custom AI agent that handles your admin, or accounting software that hooks into Google Sheets.

I’ve built everything from audiobook platforms and IoT devices to Reddit bots and 3D space combat games. When you work with me, you’re getting someone who doesn’t just design websites. I build and ship real software for a living.

Training & YouTube

Hands-on. Practical. No fluff.

I’ve delivered “DevOps for Operations” workshops and written training courses where people learn by doing: real AWS infrastructure, real CI/CD pipelines, real monitoring stacks. My approach: starter code and lots of demos. Always.

Community

London Infrastructure As Code Meetups

For several years I ran free community meetups in London, exploring infrastructure-as-code topics with hands-on sessions and live demos. Currently on hiatus, but the community and the learning lives on.
