FIELD NOTES
I use Field Notes to write about things I’ve been reading, researching or thinking about across software engineering, websites, accessibility, search, AI and technical leadership.
Some notes are deeply technical. Others are practical observations, questions or ideas I think are worth exploring.

More Field Notes
Each note explores a question, idea or area of technology I think is worth looking into.

AI coding agents can now inspect repositories, run commands and make changes across a project. GitHub's new sandboxing approach raises an important question about how much access we should actually give them.

What is WebMCP, and why are Google, Cloudflare and others looking at ways for AI agents to interact directly with websites? We look at what it could mean for businesses and the way websites are built.
According to the National Cyber Security Centre, half of small businesses experience a cyber incident each year. Here are six practical questions that can help you understand how prepared your business really is.

Google Search is changing, and it's leaving a lot of business owners wondering whether the rules have changed too.
Modernising an existing system does not always require a complete rewrite. Here is how to reduce risk and improve it gradually.
If one of these notes sounds close to a problem you’re dealing with, I’m happy to talk it through.
