I grew up in Croatia and have spent the last decade and a half in Melbourne, Australia. By profession I am an engineer — the kind who works on safety-critical systems: tunnels, industrial plants, railway infrastructure. PLC software, SCADA systems, functional safety standards with names like AS61508 and EN50128. Large projects with many stakeholders and the kind of consequences that make you careful.

Alongside that, I have always been drawn to questions that do not fit neatly into a requirements document. Consciousness. What it means for a system — any system — to be aware of itself. Why formal logic cannot close on its own foundations, and what that implies about everything built on top of logic. Whether free will is real or a useful fiction, and whether that distinction matters.

The two sides are not as separate as they might appear. Systems engineering is, at its core, a discipline about managing complexity — about understanding what a system does, what it should do, and where those two things diverge. Consciousness studies, philosophy of mind, and contemplative practice are the same inquiry applied to the most complex system any of us has direct access to.

For the better part of a decade I have been trying to build TrustSphere — a platform for communities that operate on gift economy and liquid democracy principles rather than money. It has gone through several iterations and has not yet become what I want it to be. I keep returning to it.

This blog is a place for writing that does not belong in a pull request or a safety case. Topics vary. Some posts are about ideas I have been reading; others are attempts to think through something in public. Nothing here is finished thinking.
