Software delivery
From commit to production: build, test, release, and the evidence trail that shows what shipped and why. Fewer hand-offs, faster feedback, and delivery that holds up to an audit.

Making the climb from commit to production less steep.
Notes and working opinions from a platform engineer on the software development lifecycle, internal developer platforms, and putting agents to work in real delivery pipelines.
01 · Practice
What I think about, and write about.
Platform engineering
Internal developer tooling that other teams choose to use. Paved roads, sensible defaults, and a platform run like a product, with real users and a real feedback loop.
Agentic engineering
Putting autonomous agents to work inside real delivery workflows, with the context, guardrails and review that make their output trustworthy rather than merely fast.
03 · Side projects
What I build for the fun of it.
Outside work I keep a project of my own going, and it sits where three interests meet.
Mapping
Making places, routes and geography easier to see, explore and plan around.
3D modelling
Working in three dimensions: modelling spaces and objects, and learning what it takes to get them right.
AI coding
Building with AI coding tools and agents, and finding out where they help and where they need a firm hand.
04 · About
Hi, I'm Gary.
I'm a full-stack developer and platform engineer, based in London. My day job is building internal developer tooling for other engineering teams, which means I spend a lot of time on the unglamorous parts of software delivery that decide whether a team ships calmly or painfully.
25+
years in infrastructure, DevOps and software delivery
12
years building platforms, including data and data analytics platforms
I write here to think in public: what works in the delivery lifecycle, what a good platform feels like from the user's side, and what changes when autonomous agents join the team. Opinions are earned from practice, and I try to say what I've seen rather than what's fashionable.
Away from the keyboard I'm outdoorsy and adventurous. I enjoy hiking, sport, photography and anything that gets me outside.
