About me

I'm a Senior Systems & Applications Engineer based in Tipperary, Ireland, with a background spanning web hosting, legal tech, CDN infrastructure, fintech, and education platforms.

I thrive in forward-thinking environments where I can improve the performance of vital infrastructure and products used by large, distributed teams. I take a structured, ITIL-aligned approach to service delivery — combining technical depth with clear communication.

Most recently at Fastly, I worked directly with enterprise customers including Stripe to resolve high-impact issues, optimise service performance, and deliver coordinated solutions across teams.
