About
Hi, I'm Debbie O'Brien
I help developers work with AI agents — testing, shipping, and teaching the craft. Former Microsoft TPM on Playwright, GDE, now building and using multi-agent workflows every day as an Independent Developer Educator.
I am a Google Developer Expert in web technologies, and a former Microsoft MVP, Cloudinary Media Developer Expert, and GitHub Star. I still love Vue and Nuxt, and I spend most of my teaching time on Playwright and how AI fits into modern developer workflows. I speak at meetups and conferences around the world, including Antarctica.
I am Irish and live in Mallorca, Spain. When I am not writing code you will find me running, cycling, skiing, doing body combat, or training Taekwondo. I am a 4th degree black belt.
