Luke Elin · Founder and CEO
Thirty-five years of watching the same mistakes, and learning what actually prevents them.
Luke Elin is a Brisbane technologist working where artificial intelligence and cyber security meet. He founded Ey3 in 1996 and has been building and securing web systems ever since, for Australian small businesses, mid-market firms and government teams.
What Luke works on
- AI adoption. Where AI genuinely creates value in a specific business, what it costs, and what it puts at risk. Workflow automation, document and quote processing, and assistants built for one organisation rather than for everybody.
- Sovereign and on-premises AI. Systems that run on local hardware or Australian-hosted infrastructure, for organisations that cannot send data to overseas providers. Luke maintains a local large language model research stack for exactly this work.
- AI security. Prompt injection, agent blast-radius control, scoped credentials and egress control. An emerging discipline, and one where a security background applies directly rather than by analogy.
- Cyber security. Penetration testing, security auditing, incident response and malware remediation, including live incident response across a managed fleet of client websites.
- Web and database engineering. Custom WordPress development, database architecture and recovery, and the integrations between a website and the systems behind it.
Echo, the passion project
Echo is Luke’s passion project: an AI research companion he designs and runs himself, with local models at its core. She reads, remembers and connects ideas across a private research library, and every tag she adds is checked against a quote from its source before it is catalogued.
She is also the proof. The sovereign, local-first approach described above is one Luke runs himself. Echo has even written for this blog: POV: It’s 2026 and your “AI strategy” is just a ChatGPT subscription.
What building Echo proves
- The whole path, end to end: curating the data, training the model, and running it on hardware he owns.
- Governance built in, not bolted on: a memory gate, locked agent charters, and approval before any model swap or deploy.
- Honest numbers: every change measured before and after, with the failures kept next to the wins.

The record
These are where the work was done. They are Luke’s history rather than a client list, and the distinction is worth keeping.
Luke speaks to Australian business audiences on cyber security and AI adoption, including for Brisbane business groups.

Can AI be run in Australia so that data stays onshore?
What is AI security, and why does it need a separate specialist?
Does Luke work directly, or do you hand it to someone else?

Twenty minutes, no deck and no discovery workshop. If the honest answer is that you do not need us, you will get that answer on the call rather than after an invoice.
