About

Or, why every team secretly needs one

Developers are focused on shipping features and hitting sprint goals. They need help making that process smooth and safe.

Ops are watching the AWS bill, worrying about maintainability, hoping they won't get woken up at 3am.

InfoSec & Governance are responsible for security and data integrity — but often don't have many levers to pull.

Marketing just want the campaign out the door, but all the red tape makes it feel impossible.

The rest of the business needs to be listened to — and where there are efficiencies to be found... so who helps?

DevOps — or DevSecOps, Platform Engineering, or "Sys Admin who has hung around with Devs too long" — gets alongside all these teams and builds automated tooling to make everyone's lives easier.

That's what I do. I've been doing it for over 25 years.

I have developed a worrying tendency to write in the third person while producing websites. I'm working on it.

DevOps Engineer

Primary DevOps engineer responsible for transforming the entire technology platform — from small, unmanaged golden image servers to a full Kubernetes platform on AWS. Mentored a junior engineer into a capable DevOps professional. Now leading technical AI adoption across the organisation alongside continued platform optimisation.

HighWire Press / MPS

DevOps Engineer → Systems Operation Manager

Joined Semantico as they were acquired by HighWire Press, then MPS Limited. Grew the DevOps team and learnt a huge amount — containerised ~100 Java and Go applications with Docker Swarm, Jenkins and Ansible. Introduced centralised logging, OpenTracing and security scanning. Stepped up to manage the UK Operations team across Belfast, Brighton and Los Gatos.

Pinnacle Internet / Precedent

Junior Systems Administrator → Director of Technical Services

Started as a Junior Sys Admin at Pinnacle, one of the UK's first B2B ISPs — installed their first datacentre server and was promoted within six months. When Pinnacle was acquired by Precedent in 2003, grew the hosting offering into a profitable multi-datacentre, geographically disparate service with offices across the UK and Australia. Customers included BMA, Parkinson's UK, Wildlife Trust, British Heart Foundation and Anthony Nolan.

From unmanaged to auto-scaling, auto-healing, secure by design
Platform

The Platform Journey

Golden image servers → Docker Swarm → Kubernetes on AWS EKS. Designed auto-scaling with Karpenter, multi-environment deployments, and Helm-based release management. Each step was deliberate — proving value before moving to the next level of complexity.

CI/CD

Pipelines for Everything

Replaced a fragile deployment process with proper CI/CD pipelines for every service — from PHP APIs to React frontends. Developers went from manual deployments to deploying via pull request with automated testing, linting and security scanning.

Observability

See What's Happening

Introduced full observability where almost none existed — Prometheus, Grafana, Loki for logs, NewRelic for APM, uptime monitoring and alerting. Teams can now see what's happening in real time rather than finding out from customers.

Security

ISO 27001:2022

Transformed the security posture from unmanaged to achieving strong compliance against ISO 27001:2022. Significantly improved AWS CIS benchmark scores. Introduced vulnerability scanning, dependency auditing and security-by-default practices.

IaC

Infrastructure as Code

All infrastructure managed via Terraform and Ansible — from Kubernetes clusters to DNS records. Reproducible, auditable, and version-controlled. No more snowflake servers.

Culture

Culture Change

Empowered developers to own their deployments. Introduced environment parity, feature branching, contract testing and a hackathon platform for innovation. Built a culture where "it works on my machine" is no longer acceptable.

AI & Innovation

Using AI as a force multiplier for a small DevOps team
Multi-Agent

Agentic Software Auditing

Built a multi-agent pipeline that autonomously audits an entire software estate — investigating every git repo, identifying software versions, checking for end-of-life risks, and producing a prioritised upgrade roadmap. Agents self-improve between passes.

Multi-AgentSelf-ImprovingPython
Compliance

AI-Assisted ISO 27001

Created tooling that uses AI to build ISO 27001 evidence matrices — mapping controls to real evidence, generating audit preparation materials, and identifying gaps. Turned months of manual compliance work into days.

ISO 27001Evidence AutomationFastAPI
Framework

AI-Powered Investigations

Developed a structured "AI-first with human verification" framework for DevOps troubleshooting — with reusable skills for querying Grafana, Kubernetes, AWS, and Jira. AI does the heavy lifting; humans make the decisions.

Policy

AI Standards & Governance

Part of the team that authored the organisation's AI policy. Personally built the reusable skills library — enabling consistent, safe AI-assisted development across multiple teams. Skills cover everything from ticket creation to TDD to infrastructure debugging.

Note: The examples above describe the type of work I do with AI. Specific implementations are proprietary — but I'm happy to discuss approaches, architecture and lessons learned.

Tools & Stories

The fun is in the choosing — and the explaining why
Local Dev

Tilt

Gave developers a one-command local Kubernetes environment. Instead of a 40-step README that nobody followed, they type ./up.sh and get a full stack with hot-reload. The number of "it works on my machine" conversations dropped to near zero.

Autoscaling

Karpenter

Replaced the Kubernetes Cluster Autoscaler with Karpenter and watched nodes spin up in seconds instead of minutes. The right-sizing alone justified the migration — no more paying for nodes that are 20% utilised because the autoscaler can't scale down gracefully.

Logging

Loki (not Elasticsearch)

For a small team, the operational overhead of an Elasticsearch cluster is brutal. Loki gives us grep-at-scale with a fraction of the resource cost — and it speaks the same language as our Grafana dashboards.

Packaging

Helm

Templated 20+ microservices without losing sanity. A shared base chart with per-service values means a new service goes from "code complete" to deployed in all environments in under an hour. The trick is knowing when not to abstract.

Migration

Golden Images → Docker

The first step wasn't Kubernetes — it was convincing everyone that "we'll just update the server" isn't a deployment strategy. Docker gave us reproducibility. Once people saw that a container built locally was identical to production, the rest followed naturally.

Daily Driver

AI as a Teammate

When you're the primary DevOps engineer, you can't afford to spend three days researching every decision. AI assistants became my rubber duck, my second opinion, and my documentation writer. The key is knowing what to trust and what to verify.

Outside Work

Life

Fantastic family. Gaming. (Watching) football. Podcasts. Many things computer-based.

I've helped lead Breakfast Church (in various forms) at Maybridge with a great team of people for over 26 years.

I live in Worthing, West Sussex — close enough to the sea to feel smug about it, far enough from London to avoid the commute.

Walking & Audiobooks

Started doing extra walks for a workplace step challenge for Diabetes UK — and discovered that if you find an unputdownable audiobook, you have to keep walking to find out what happens next.

I now average a couple of books a month along Worthing beach. This year's themes: epic fantasy, comedians with autism, and dystopian comedies.
