About

Ciarán McCormack

I have worked in software engineering for over twenty years. I take on CTO and CISO roles, part-time or on contract, and hands-on engineering across web and mobile apps, backend systems, databases and infrastructure.

Raiblin Services Pty Ltd is my company. Consulting comes first. Alongside it, Raiblin releases my own software: the Awaken engine, and the games and tools built on it.
