About Me

I build fintech systems at Booking.com — before that, e-commerce microservices at THG and telecom platforms at Samsung R&D, with an MSc in Computer Science from Trinity College Dublin. I like work that spans the whole stack: scroll-driven 3D up front, distributed systems underneath, and the odd blockchain experiment in between. When I'm not shipping, I'm at a hackathon or a meetup.

  • 5+ years building for the web
  • Frontend, backend & cloud
  • 3D / WebGL experiences
  • Blockchain & Web3 curious
