02 / model lab
What each model delivers today: how many brands it recognizes, how accurately, how fast, and how much it saves.
Identifies the brand, sub-brand and exact SKU of every product on a shelf.
Added 7 new SKUs at 97% accuracy with no new labeling round — ~$800 saved per extension.
Tells which of 11 store types each visit belongs to, from its photos.
Three of every four visits are classified with no human review; only doubtful ones reach a person.
Recognizes the cold equipment in a store and which brand owns it.
Brand-level cooler audits answered in 25 ms per photo, live in production.
Finds signage, fridges, shelving, entrances and address plates in store photos.
Replaced a paid LLM step: up to 160× faster, at about one cent per thousand photos.
Locates every product on a crowded shelf so each one can be recognized.
Turns one shelf photo into ~41 recognized products in under a second.
Spots shops in street-level video to map new points of sale.
Annotators start from the model's boxes instead of empty frames.
03 / ai agents in operations
Two agent systems I built and run: one answers business questions from live data, the other runs field work on WhatsApp.
5.8k research questions + 806k field-capture messages.
LLM calls, data queries, photo checks, transcriptions.
Captured through the agents and checked by AI on arrival.
Field teams on WhatsApp, ops and sales on Slack.
research-agent questions / month
* October through the 21st
LLM agents on Vertex AI · custom MCP server · WhatsApp Cloud API · speech-to-text · BigQuery · PostgreSQL/PostGIS · Pub/Sub · Slack
04 / more work
Real-estate intelligence, quant research, a city-scale retail census and an on-chain game economy.
Every listing gets a model-estimated fair value, so buyers instantly see what is under- or over-priced.
Each listing is checked before buyers see it — inconsistent or suspicious ones never reach them.
The real production model, running in your browser. Change any field and the estimate updates instantly.

Machine-learning strategies, run by AI agents: one reads markets, one sets risk limits, one runs the book. 102 strategies were stress-tested with real fees — only 8 made the portfolio.
Out-of-sample (2025+): profit factor 1.32 over 612 trades · beta to the S&P 500: 0.02 · simulated results, not live returns.
A living census of traditional retail: where every store is, how much potential each zone holds, and where field teams should go next.
Every reward, trade and stake in this fantasy RPG settles on-chain through smart contracts I wrote.
