Senior PHP Developer & Full-Stack Engineer
Software engineer based in Cork. I’ve spent 20+ years building web applications — co-founding Finland’s first influencer marketing company, and now developing healthcare platforms in Ireland.
Current work
AssetTrak at Healthcare21
I maintain and develop AssetTrak, a configurable PHP/Symfony platform for tracking service and maintenance of medical equipment. It’s used by decontamination, logistics, and repair providers across Ireland, the UK, and the EU. My work covers new features, ongoing maintenance, and UI development with JavaScript — jQuery and React.

RPG Notes
A bridge between GM notes in Obsidian and players. Session notes sync from GitHub for players to read online, and new notes players add sync back to GitHub and the GM's Obsidian vault. It also exposes an MCP server, so players can bring their campaign notes into their own AI tools as a kind of shared memory.
Personal project
Fantasy Grounds Chatlog Analyzer
A hobby tool that turns Fantasy Grounds chat logs into session insights — dice stats, combat outcomes, and player participation.
