Management platform for in-person business networking — events, tickets, membership and multi-franchise finance, moving real money.
nearly 200 — active members using the platform to pay dues and get into events
A three-layer stack that lets an AI agent research the market, decide and place real orders — with the safety catch closed by default.
$2 — the real order that proved 653 green tests weren't enough
An agent that closes the month: a won deal in the CRM becomes a receivable in the ERP, the bank statement is matched against the ledger, forecasts are posted per project. Ten of the fourteen never write anything anywhere.
4 of 14 — the only ones that can write to a system — and all four stop, show the table, and require a typed "yes" first
You draw an area on the map and the system returns, marked, every solar panel on that roof — in any city covered by satellite imagery.
0.887 — the real mAP, after I found out my test set was contaminated
You give it a topic. It writes the script, narrates it with a cloned voice, generates the images, syncs the captions, animates the mascot and delivers the MP4 ready to publish.
48 — videos assembled from topic to MP4, with no manual step in between
A 2D roguelite where physics is the mechanic: no weapon was ever coded, they all emerge from material properties.
93 — invariant tests — the physics has to keep obeying its own laws
Finding where each component sits inside an electrical engineering drawing — and manufacturing the training set that teaches it, because hand-labeling does not scale.
4 classes — with the box computed from the symbol's own geometry, not drawn by hand
The ERP that carries an order from the customer to the sealed box — modeling, approval, production, painting, finance and inventory in one place.
7 stages — from customer order to sealed box, each with an owner and a checklist
Automated WhatsApp support that answers instantly, qualifies the lead, feeds the CRM on its own, and only pulls in a person when it's worth it.
2% → 3.6% — the company's conversion rate before and after the bot, in a high-ticket business
Thirteen targeted patches that make surface reconstruction training faster without changing a comma of the final result.
≈10% — more iterations per second in the training loop — +9.5% measured, with identical geometry
Five market techniques everyone repeats, stress-tested until what's left is an answer you can trust.
−0.6%/yr — what beta actually paid, where the CAPM says it should pay a premium — t = −0.16, indistinguishable from zero
You photograph a painted miniature with your phone and get back its mesh, ready for Blender and for the resin printer — with no desktop scanner involved.
US$0.70 — the GPU cost to digitize one piece, after I measured that the four-hour version was no better
Brazilian public environmental portals demand a CAPTCHA for every single file you download. I trained the model that reads it and took the human out of the loop.
82% — of CAPTCHAs accepted on the first try by the server itself, with the right letter case
Two Excel macros that post the month's progress billing and match every ERP invoice to the right spreadsheet row — tested against the real spreadsheet before going anywhere near it.
20/20 — asserts passing on a throwaway copy of the real spreadsheet — and getting there surfaced a bug that was already running
You write the alphabet once on a drawing tablet and the tool generates any text in your handwriting — pen pressure included.
720 — samples of my own handwriting, ten per glyph — this is what makes the same word come out differently twice
A full compiler, from lexical analysis to ARMv7 Assembly that runs on the simulator — in plain Python, with no dependencies.
55/55 — tests passing, from token recognition to the assembly that runs on the simulator
Open source personal finance manager you host yourself — your financial data never passes through any company.
