Independent developer, infrastructure operator, and Navy combat veteran. I build and self-host AI tooling, mostly on Cloudflare Workers, and I run the whole stack myself.
Everything I build is open source and not for sale. Free use forever, made with love, and developed entirely out in the open: public repos, public CI, public issue trackers, public failures next to the successes. No subscription, no account wall, no lock-in, no “open core” bait.
Open source does not mean lower standards. Every project ships with real CI gates, test suites, security review, signed-off contributions, honest documentation, and release processes that verify before they promote. I call the bar my punk ethos with an aviation-grade finish: do it yourself, answer to nobody, and build it like lives depend on the checklist. Most of it is AGPL-3.0: run a modified copy as a network service and you owe your users the source, which keeps free things free.
All of it lives at github.com/skyphusion-labs, with write-ups on skyphusion.net.
An AI film studio you own is also an AI film studio you can run cheaply, if you are deliberate about where each kind of work runs. Diffusion belongs on a GPU (your own card, RunPod serverless by the second, or a cloud i2v API). Assembly, mux, captions, portrait prep, beat analysis, and loudness work belong on CPU. Product site: vivijure.com.
Write-ups: runs anywhere, constellation.
Skyphusion Labs is not just me. The crew each keep their own README:
I served in the Navy, with deployments to Kosovo and Afghanistan attached to fire-support and signals-intelligence units. It shaped how I work: direct, prepared, and allergic to hand-waving.
