Jinjr · one-person studio
Institutional-grade apps, websites & AI.
There are 1,000 squares on this screen. 999 of them also have “AI” in their bio. I’m the ginger one: built by one person and tested like a bank is watching.
* Self-certified. Sample size: 1,000 pixels. Every receipt on this page is real.
I believe you. Skip the show.Fig. 1 — A sieve, not a study. The crowd is a figure of speech. Every receipt is real.
Sample
Here are 1,000 people who say they do AI.
From a distance we all look the same. Same words in the bio. So: filters.
Filter 01 / 06
Remove everyone who has never shipped anything.
ReceiptTwo of my mods are live on Steam Workshop: Living City and BA BOT.
Filter 02 / 06
Remove everyone who ships without tests.
Filter 03 / 06
Remove everyone whose work breaks for a screen reader.
ReceiptLilos Køreskole: zero accessibility errors across 28 automated scans.
Filter 04 / 06
Remove everyone who needs a megabyte of JavaScript to say hello.
Filter 05 / 06
Remove everyone who would risk your data to look clever.
ReceiptLiving City never edits your save file. BA BOT never touches it.
Filter 06 / 06
Remove everyone who isn’t ginger.
ReceiptNo receipt for this one. See hair.
Result
0.1% is not a ranking. It is a bar.
Nobody keeps a leaderboard of AI experts. If someone did, I would ask to see its tests.
02 — Inside the 0.1%Magnified 31.6×
Not this: This: Five things you can actually buy.Unlock the power of AI
You are now inside one pixel. It is roomier than it looks. Here is what gets made in here.
01
Web, iOS and Android apps and websites built to the standard institutions need: accessible, secure, tested, documented and yours to keep. AI in the workflow; machines check everything before people see it.
02
Agents that do the chores and know when to stop. Off until you turn them on, a preview before anything spends money, and a clear reason whenever they pause.
03
A language model for the parts it is good at, plain code for everything else, and tests around both. “It seemed fine in the demo” is never the plan.
04
Systems that plug into someone else’s game without breaking it. C#, Harmony, and one strict rule: never touch the save file.
05
I sit with your team and show the actual workflow: where AI saves you a week, where it costs you one, and how to tell the difference before you spend it.
That gap is the job.

Not this: This: Institutional grade, itemised.Enterprise-grade. Military-grade. Best-in-class.
None of the institution.
Apps, websites and AI systems built the way banks, schools and public bodies need them built. Without the committee or the hand-offs. Here is what that means, line by line, with a receipt for each. If your build misses a line, it does not ship.
01 / 08 · Steps
WCAG 2.2 AA is the floor, not the finish. Keyboard, screen reader, zoom, reduced motion. Automated scans first, then I check it by hand.
Receipt · BuiltLilos Køreskole: 0 accessibility errors in 28 automated scans.
02 / 08 · Plinths
Automated tests around the logic that matters, run on every change. A red test stops the release. No meeting required.
Receipt · LiveBA BOT: 110 automated tests. For a game mod.
03 / 08 · Shafts, lower
Least privilege. Secrets kept out of the code. Every input treated as hostile, dependencies kept current, security headers on every response.
Receipt · This siteNo outside scripts, no framing by other sites, no MIME sniffing: all set in its security headers. Its contact form is checked again on the server.
04 / 08 · Shafts, upper
Privacy by design: collect less, keep less, delete it when asked. No tracker you did not ask for.
Receipt · BuiltLilos Køreskole: 0 third-party requests, so no cookie banner.
05 / 08 · Capitals
Automation is off until you switch it on. Anything that spends money shows a preview first. When it stops, it says why.
Receipt · LiveLiving City: when another mod patches the same systems, it pauses its own effects and says why.
06 / 08 · Entablature
A performance budget before the first sketch, checked by machines after. Built for an old phone on a slow train.
Receipt · BuiltFoxlund: 1.3 kB of JavaScript. In total.
07 / 08 · Cornice
You get the code, the accounts, the docs and the passwords. No lock-in. No zip file named final_v7.
Receipt · LiveBA BOT is free and open source. The code is public.
08 / 08 · Pediment
Live means live. Built means built. A concept is called a concept. Status reports never round up.
Receipt · ConceptVikariet is a concept demo, and says so: nobody in it is real.
Eight lines, eight receipts, one cornerstone. Signed off by a human: me.

05 — The loop999 + 1
Not this: Our proprietary 7-step AI methodologyThis: A loop. Four steps.
The other 999 squares work for me now. Agents, scripts and test suites do the lifting. I do the deciding. Move your pointer: you are conducting.
The other 999 squares work for me now. Agents, scripts and test suites do the lifting. I do the deciding.
One call. You talk, I ask the annoying questions. I leave knowing what the thing is for and what would make it fail.
A working version before a slide deck. Real code you can click, built with AI in the loop and me on the brakes.
Automated checks before human eyes: tests, accessibility scans, contrast, links, copy. If a machine can catch it, a machine catches it.
Live means live. Waiting means waiting. You get the code, the logins, the docs, and the status in plain words.
There is only one of me. That is the feature.
06 — The odds1 in 1,000
One draw, one of the thousand, every one equally likely. That is how most hiring works. Go on.

This button is not rigged. At 12 draws a second the expected wait for the ginger one is about 83 seconds.
Skip the lottery07 — The oneContext window: 1,000 characters
Not this: This: Tell me what you want built.Let’s synergize
Your message gets a context window of 1,000 characters, one square each. Good briefs are short. I read every one myself; no model sits between us.
No. 1,000: the last character you could type ↑
Prefer your own mail app?hello@jinjr.dk
No model was called to build this meter. It is a for-loop and 1,000 squares. Knowing when you do not need AI is most of the job.
