GP-01 worked up this idea: a sample project, described as if it were to be built. It is not a client reference — the products actually shipped are on the desktop.
On-site intervention: observe flows, map friction points, deliver actionable recommendations, deploy tools (with or without AI) and train teams. Goal: measurable gains in a few weeks.
Mission
We embed in your organization to understand how work flows (people, tools, data), then turn those findings into actionable recommendations and tools that are actually used.
What we do on site
—Flow observation: from the initial request to delivery (sales, ops, support, admin…)
—Targeted interviews: operators, managers, leadership (real problems, not assumptions)
—Mapping: steps, wasted time, friction points, error sources, dependencies
What you get (concrete)
—Readable diagnosis: what blocks, why, and the impact (time/quality)
—2–6 week action plan: quick wins and foundational work

Training, documentation, and handover
An idea worked up by the workshop — a sample project, described as if it were to be built. The products actually shipped are presented below.
Available fully remote, immediately
Pasto — software workshop
I design and ship complete products: an iOS app with its firmware, a SaaS platform with its database and its agents, a showcase site with its back office. From the first mockup to production, alone, with agents to keep the pace.
10 products are running today, one of them used every day to run the workshop itself. What you see above is not a showcase: every icon opens a real product, with its screens and its technical choices.

The products
9 products — 4 online, the others in pilot, internal or under construction.
Asterlogia
Your sky, read in a real voice
A conversational agent that knows your birth chart, your transits and the traditions — and that doesn’t recite: every astrological claim goes through an evaluation harness before it is served. Astrology taken seriously, technically.
Evaluation harness: 99.7% factual fidelity across 1,191 assertions
20 years of municipal bulletins and council minutes, searchable in plain language. Every answer cites its sources: you can check, document in hand. A town’s memory, finally within reach.
To live in their own city, a resident juggles ten applications: parking with a private operator, buses somewhere else, events across three Facebook pages, the town hall by phone. A single app replaces them all: pay for parking, follow the bus in real time, report a pothole and watch the roads department handle it, ask a municipal assistant how to sign a child up for school lunches. On the town hall side, a dashboard that finally shows the digital life of the city.
Expo SDK 55 app (iOS, Android, web) + Next.js 16 town hall dashboard, Turbo monorepo
In-house design system of 26 components shared between the app and the dashboard
Designed for Cagnes-sur-Mer (53,000 residents), white-labeled for any municipality
Your town, online in a month
The foundation exists and runs: it is configured city by city — your colors, your name, your services, your data. Once the events calendar, the news, the bus stops and the parking zones have been handed over, your town has its application in under four weeks.
✓White label: your identity, not ours
✓Your data stays yours — nothing handed over to a private operator
✓App Store and Google Play publishing handled
✓Town hall dashboard included: reports, content, usage statistics
✓Staff training and migration of the existing setup included
The platform that runs Pasto: clients, projects, quotes, communications. An agent with 19 tools works in it continuously — and asks for human approval before every sensitive action. It is the workshop’s own workshop.
Agent with 19 tools, structured outputs, human-in-the-loop
Hardware-key authentication, audit log
23 migrations, used every day
This is the agent that designed and coded the site you are looking at

Pasto
A sensor in the soil, an app in your pocket
The garden, measured: soil, air, light, movement. The app predicts watering from the weather and the water balance — the sensor keeps watch, you do the gardening.
SwiftUI iOS app, StoreKit 2 subscriptions
Zephyr firmware (nRF5340)
FAO-56 water balance fed by the weather

Prosopon
Faces that speak in real time
AI video avatars in real time: the voice, the face, the lip sync. Nine model providers orchestrated behind an in-house runtime.
9 providers for LLM, TTS, lip sync
C++/WebGPU runtime

Encyclopedia
395,000 plants, every fact traced
A botanical corpus of 395,000 taxa, documented in 5 languages, where every field knows its source. The LLMs write, a tool-equipped judge checks, and costs route the models.
Ingestion pipeline over 5 sources (Kew, TAXREF, iNaturalist…)

Segmentia
Being cited by AI can be measured
When a customer asks an AI “which provider should I pick?”, Segmentia measures whether a small business shows up in the answer — and helps it show up. Delivered turnkey to its client, from design to production.
A 2D run and gun where you don’t destroy: you convert to the light. Twelve signs of the zodiac are possessed, each guarding its house; the ones you free join a clan that grows as the crossing goes on. Flat-out running, dashing, wall sliding and charged shots — the snap of the great era of action platformers, in a browser.
Phaser 3 + TypeScript + Vite, packaged as an iOS and Android app via Capacitor
Ground and air dash, wall kick, dash-jump, buster with three charge levels
Retro sound effects generated in WebAudio — no audio files shipped
Levels in the Tiled format, checkpoints, bosses with three patterns and an enraged phase
Every project has its design dossier: web pages built by hand to draw the product before writing it. One screen, one decision, one comparison of directions. We look at them, we discuss them, we decide — and what gets approved serves as the specification. Seven of them are open on this site, from the complete dossier for an app to the twelve boss mechanics of a game.
The navigable mockup comes before the first table in the database — what has not been seen on screen is not decided.
Nothing ships without going through the evaluation harness: 1,191 assertions replayed on every change, adversarial tests, and one regression is enough to block a release.
Costs and latency are measured in production, not in meetings: tracked per user and per model, from day one.
Working together
An engagement, a product to ship, a prototype to settle: write to me with what you want to deliver and by when. I answer with a way to do it — and, when it helps, a clickable screen rather than a ten-page quote.
