Senior Software Engineer. 20+ years delivering software.
Thinking carefully about engineering, delivery, and the pragmatic use of AI.
What I do
I build and ship software — full-stack, backend-leaning, with a strong interest in product thinking and delivery quality. I've worked across consulting, product companies, and startups. Right now I'm focused on how experienced engineers can work well alongside AI tooling without losing their judgment.
I'm currently available for new opportunities. Get in touch.
