About
About me
I'm a software engineer based in Dublin. I've spent years designing, building and deploying web and mobile products end to end — from database schema and APIs to front-end, mobile apps and production infrastructure.
I recently completed a Higher Diploma in Science in Computing at the National College of Ireland, graduating with First Class Honours. I use AI coding tools such as Claude Code every day, and I care about clean architecture, data security and software that holds up in production.
Some of the products I've built are published under ZitStack.
