WRITING CODE AND READING BOOKS
I'm an experienced engineering and product leader. My career started in R&D companies, building old-school AI tech: expert systems, computer vision and signal processing. I've since built apps and systems for companies from startups to massive enterprises; in industries from retail to fintech to healthcare to education. I've worked at all levels from engineer to CTPO. I build things.
This site is where I write about the things I care about. I'm an engineer and I care about a lot of technical things. There are also books, travel, photography and what it's like to attempt to restore 6.5 acres of neglected land in the North Wales countryside.
