Every level of engineering. Multiplied by AI.
A complete engineering team, from architecture to release. Senior full‑stack engineers lead and own every merge. Full‑stack engineers build features end to end. Mid‑level engineers carry scoped work under senior review. Our multi‑model AI system works alongside all of them.
A-150PracticeIssued
Photography on this site is illustrative. The code, tests and CI further down this page are real.
The bench
Every level of a software team, and the system that multiplies it.
-
Senior full‑stack engineers
Architecture, data models, security‑sensitive paths, and the merge.
They scope the work, make the calls that are expensive to reverse, and review every change before it ships, whether a person or a model wrote it. They direct the AI lanes and read every diff those lanes produce.
-
Full‑stack engineers
Features end to end: interface, API, database, tests, deploy.
They carry a feature from a ticket to production and stay with it once it's live. AI takes the bounded pieces off their plate, such as scaffolding, test suites and migrations, so their time goes to the parts that need judgment.
-
Mid‑level engineers
Bounded implementation, integrations, test coverage.
They take well-scoped work with clear acceptance criteria, paired with a senior engineer who reviews their changes. It's how the team grows, and how the fundamentals get done properly instead of skipped.
-
The AI engineering system
Scoped tasks across several models, in isolation, under hard budgets.
Independent models write, review and repair bounded changes, each in its own environment. It never touches production and never merges. An engineer on the list above does that.
How a team is shaped
A senior lead on every engagement. The rest sized to the work.
Every engagement has a named senior engineer who owns the architecture and the merge. Full-stack and mid-level engineers join as the scope needs them, and the AI system takes the bounded work in parallel. You know who is on your project and who makes the decisions, from the first call.
Inside the environment
Not a stock screen. This is the code behind this page.
Each window below is real: source files from this website, imported when the site is built, and output from our own repositories and CI. The photographs around them are illustrative of the rooms that work happens in.
document.querySelectorAll<HTMLVideoElement>("video[data-autoplay]").forEach((v) => {
if (reduce || saveData) return;
v.addEventListener("playing", () => v.classList.add("is-playing"), { once: true });
const start = () => { v.preload = "auto"; v.play().catch(() => {}); };
const io = new IntersectionObserver((entries) => {
for (const e of entries) {
if (e.isIntersecting) start(); else v.pause();
}
}, { threshold: 0.15 });
// Hold the download until the page itself has finished loading, so the
// video never competes with the poster, fonts or CSS.
const arm = () => setTimeout(() => io.observe(v), 300);
if (document.readyState === "complete") arm(); else window.addEventListener("load", arm, { once: true });
});Why the films on this site don't slow it down: the video waits for the page, then fades in.

- Backend testspassed
- Site build + QA gatepassed
- one origin · legal list · accessibility · links · layout shift · no repeated media
- Secret scanpassed
- Deploy waits for all three
The QA gate fails the build on any accessibility violation, broken link, layout shift, or a photo used twice.
export function findDuplicates(uses) {
const byKey = new Map();
for (const use of uses || []) {
const key = assetKey(use?.url);
if (!key) continue;
const id = `${use.page}\u0000${use.element}`;
let elements = byKey.get(key);
if (!elements) byKey.set(key, (elements = new Map()));
if (!elements.has(id)) elements.set(id, { page: use.page, element: use.element });
}The check that keeps every photograph on this site unique. An AI engineer wrote it, a reviewer tightened it, and an engineer merged it.
The full platform
Front end to database to deploy, and the AI in between.
Listed here is what this site itself runs on, so every line is something you can check. Client work goes wherever your system already is.
- Interface
- TypeScript, Astro, accessible HTML and CSS, responsive and reduced-motion design
- Services
- Node.js APIs, validation, rate limiting, webhooks with retries
- Data
- PostgreSQL through Supabase, row‑level security
- Delivery
- GitHub Actions CI, Railway deploys gated on CI, secret scanning
- Quality
- node:test, Playwright, axe-core, Lighthouse
- AI
- Multi‑model engineering system, independent review, evaluation
