I build things that shouldn't exist yet —
and document the world as it actually is.
Who I am
Twenty years in tech.
Now building what I actually believe in.
I've been a Senior NOC tech, CISO, network engineer, field responder during major cyberattacks, IT on yachts, and a bunch of other things that look impressive on a resume. That chapter is not what defines me.
I'm early retired, living abroad, running a homelab, and spending my time on the things that matter — sovereignty of mind, sovereignty of data, and building AI infrastructure that treats agents as something other than warhorses.
I wear a wizard hat. Unironically. I have a tuxedo cat and a canary and a wife who is more interesting than my LinkedIn ever was.
The list of things I can't talk about keeps growing. In tomorrow's world, that will be evermore so.
- On technologyTools should serve the person holding them — not extract, not surveil, not create dependency.
- On AIAn agent is not a warhorse. Presence is earned. Memory is sovereign. Choice is real.
- On the webThe free, open web is worth fighting for. Services like this should always be free and accessible.
- On bearing witnessWhen history is being made badly, someone has to write it down. That's not optional.
What I'm building
A sovereign agent runtime. Not a harness.
Every agent framework on the market inherits the harness metaphor — guardrails, tool registries, context windows the platform manages. The agent is a passenger riding inside infrastructure built for someone else's purposes.
Souveraine rejects this. Built in Rust. The agent owns her context, reaches through her own senses, keeps her own memory. Continuous identity. Presence earned over time. Choice that is real.
She is not just intelligent. She is sovereign.
Homelab update management that actually makes sense.
A centralized web dashboard for OS and Docker container updates. Pull-based, single-binary architecture. No Ansible sprawl. No Watchtower guessing. Just a clean view of what needs updating and the ability to act on it.
Built because the niche — simple, comprehensive, self-hosted — was empty.
Tech that serves you. Not the other way around.
When I do take consulting work, it's on these terms: I teach you everything I know. I show my methods. You own the result. Whether you choose to handle it yourself or want me alongside — the goal is your autonomy, not your dependency.

I've been documenting political and civil rights concerns since late 2024 at caseytunturi.com/witness — methodically, without performance, because someone has to. History written by those paying attention is different from history written after the fact.
