I'm Robert Hadden Jr. I build fast sites and the automation behind them. This page, and every page on this domain, is the work sample — one hand-written file, no framework, no third-party script, and two complete 3D games you can play without downloading anything.
The proof
Quantum Melanin Media is my own company, which means nobody signed off on a shortcut. Everything below is verifiable by viewing source on the page you are reading.
A 540-pixel column of emoji link cards.
One hand-written page that shows the work instead of naming it.
The part worth reading
Anyone can show you a layout. This is the thing that actually separates a finished build from one that merely looks finished.
The hero and the chess reel originally served a VP9 .webm with an
h264 .mp4 fallback. Nothing ever reached the fallback, because every
browser answers canPlayType("video/webm; codecs=vp9") with
"probably" — and then Chrome dies on the file with
PIPELINE_ERROR_DECODE about three tenths of a second in. Live, that is
a hero frozen on its poster image, on every single visit.
HTTP 200The file served fine.durationCorrect in the metadata.ffmpeg -f nullDecoded the identical file with zero warnings.canPlayTypeReported "probably" in every browser tested.-crf 34 · -b:v 800kReproduced at every bitrate, and with auto-alt-ref and lag-in-frames tuned.Every measurement agreed with every other measurement, and all of them were wrong. Only pressing play told the truth.
So the fix was not an encoder setting. It was a format to stop shipping — mp4 only,
no <source> list, nothing to fall back from. Then I wrote the check
that would have caught it: the pre-deploy harness now presses play on every video on
the page and fails the build if the clock does not move. It costs 600 KB on the hero
to be certain the hero plays, and that gate is permanent.
What ships with every build
Three tools live in this site's repository. They are the reason a one-person studio can push straight to production without a staging environment.
Regenerates every image and video on the site from their real sources — the game repositories, Amazon, Gumroad. Nothing in the assets folder is hand-made, so nothing on the page can quietly go stale while the product moves on without it.
Records genuine gameplay to mp4 by driving a headless build and capturing frames over the debugging protocol. The hero loop is real frames from the real game, which is why it looks like the thing you are about to play.
The deploy gate. Serves the repository, screenshots desktop and phone, and fails on 404s, JavaScript errors, broken images, horizontal overflow, and any video whose clock does not advance when you press play.
Other production work
Not demos. Each of these has customers, payment rails, or both.
Wellness subscription platform on Render with live-key Stripe billing. I rebuilt the auth stack in production — the original silently failed for every Google user — and shipped both sign-in paths with zero regressions on paying customers.

Trading dashboard with a charting engine I wrote by hand in SVG, because every off-the-shelf library drifted one to three pixels off the candle body — fatal when a trader is marking a precise entry.

Scans Word, PDF and Markdown manuscripts for structural typography damage — orphan fragments, false-bold sentences, headings buried mid-paragraph, and the merge bugs that survive every spellcheck.
Read the source →Sixty seconds, no mockups
A site, an interactive book with twenty-five clickable sources, a twenty-track score, three browser games and an audit practice — all of it running, all of it out of the same room. Nothing here is a comp or a concept. The music changes at 0:47 because the page on screen changes track, and the previews are real.
Every link in it goes somewhere you can check for yourself. Open the book →
Built here, all of it
Real capture from Quantum Motors 3D — a WebGL racer that runs in a browser tab with no download and no plugin. The cuts land where they do because the track was measured at 136 BPM and every clip is a whole number of bars. The game, the edit, the music and this page came out of the same room.
If you need the site and the thing that sells it, that is one conversation instead of three vendors who blame each other. Play the game it came from →
How this usually starts
If none of them describe your situation, say so in the email and I will tell you honestly whether I am the right person for it.
That is the rate for ongoing and open-ended work. Anything with a clear edge to it I quote as a fixed price instead, so you are buying the outcome rather than my clock — the three below are priced off that same rate, and you see the number before I start, not on the invoice.
$450 fixed
A fixed-scope audit of a site you are unhappy with. You get numbers, not opinions, and a written list of what to fix in priority order.
from $2,400 fixed
A site, a landing page, or a WebGL experience, built the way this one was and handed over with the tooling that maintains it.
from $1,200 fixed
The workflow currently eating a person's week. Playwright, Python, and LLM pipelines with verification built in from the start.
Tell me what is broken and what it is costing you. If I am not the right fit I will say so in the first reply rather than the third invoice.
