Cover image for An update on the red-team
An update on the red-team loop from my last post. I turned it from a one-off script into a real harness I run with one command against the whole stack. It attacks the backend, replays out-of-order Stripe events to prove a cancelled plan can't come back, and it screenshots the site and fails if the page renders as a flat white frame. That last one is a real bug I hit: the old checks passed because there were no console errors, but the entire hero was painting white on certain GPUs. I also added a tripwire that fails the build if I ever delete something already built and verified, or reintroduce a mistake I already fixed. Iterating on a live 3D site, the hard part is not breaking the thing that already worked. It runs in CI now, so every push gets checked.

Cover image for New work: I rebuilt my
New work: I rebuilt my studio site as a real-time 3D experience, then I attacked it. The visual layer is hand-written WebGL and GLSL. GPU particle cores that react to your cursor, morphing transitions between pages, adaptive performance that tunes itself to the device. All custom code, no template, no page builder. But looking expensive is only half the job. I also build and secure the systems behind sites like this: multi-tenant SaaS, Stripe billing, PostgreSQL row-level security. So I wrote an automated red-team loop in Python and ran it against my own live site: attack, triage, patch, verify. It flagged a couple of hardening gaps, I fixed them, and re-ran until it came back clean. If you want a site that looks like a high-budget trailer and holds up when someone probes it, that is what I build. Live: xkaii.studio (http://xkaii.studio)The security work: xkaii.studio/security
