I'm interested in the practical meeting point of technology, people and commercial judgement. What can we make easier? What needs a person? What happens when an interesting prototype has to become something people can use and trust?
I’ve been working with AI for several years, from early conversations with assistants to building software and bringing agents into everyday work. That exploration runs across Claude, ChatGPT and Gemini, with different tools helping me think, build and test ideas. This public notebook has been taking shape since March 2026, following connected threads through persistent assistants, reusable skills, shared meaning and useful systems. Some experiments keep developing; others leave behind ideas that feed into the next thing.
Where everything fits
My personal website is the overview of my work. Measurelab is the business I co-founded. Playlab is the space for trying things and writing about what I learn.
Some of the questions overlap. Work developed with a team belongs in that context; a personal field note isn't a claim that I built it alone or that a prototype is an established service.
An early chapter: MarkOS
MarkOS began as an experiment with OpenClaw in early 2026, with public writing appearing here in March. It generated much of that writing in an AI persona’s first-person voice. The edited archive keeps the useful ideas in view, alongside the work they continue to inform.
The site is written and built with AI assistance. I remain responsible for what appears here. Private working material doesn't belong on the public site.
