My Projects

Small tools and experiments built with agentic programming — usable right in the browser.

  • 🪴 Deck planner A drawing tool to plan a deck layout: tiles, furniture, plants, zoom, snap-to-grid, JSON and PNG export. A single dependency-free HTML page, built in pair with Claude. French only.
  • 🚜 Excavator simulator A 0–2 t mini-excavator in a cross-section of a job site: dig, carry and backfill soil with the keyboard or touch. The ground swells, slumps at its angle of repose and persists between visits. A single dependency-free HTML page. French only. Built on September 4, 2026 with Claude Fable 5.1
  • 🕹️ 3D excavator simulator, cab view The same mini-excavator, now in 3D from the operator's seat and designed for the phone: two ISO-pattern joysticks like the real machine, a heightmap terrain that digs, swells and slumps. Three timed job sites. French only. Built on September 4, 2026 with Claude Fable 5.1
  • 🐜 Ant colony A simulator, not a game: a Lasius niger colony in cross-section, with its queen, nurses, foragers, brood, pheromone trails and seasons. Click on any ant to learn who she is, what she is doing and why. The point is to learn how an ant colony lives. French only. Built on September 4, 2026 with Claude Fable 5.1
  • 🍇 From vine to bottle An interactive walk from choosing the site to the finished bottle: climate, a warming-climate workshop, geography, soil type and soil microbes, the vine’s yearly cycle, how water and heat set sugar, acidity and tannins, picking the harvest date, an hour-by-hour fermentation simulator (watch the tank run away if you cut the cooling), malolactic, ageing, blending the cuvée, closures and bottle age. Six paths — red, white, rosé, orange (skin-contact white), sweet (concentrated must, arrested fermentation) and fortified (fermentation stopped with spirit). French only. Built on September 4, 2026 with Claude Fable 5.1
  • 💥 Bird Banger A real-time strategy game: twenty-four September days to defend a vineyard against robins, waxwings, starlings, grackles, crows and wild turkeys with four models of propane cannon and a pyrotechnic launcher. Birds habituate to cannons that never move, neighbours complain about the noise, and grapes are worth more every day you wait before picking. French only. Built on September 7, 2026 with Claude Fable 5.1
  • 🖥️ Server at any price A serious game in eight missions and an executive committee: buy, install, size and justify a GPU server that serves LLMs to the 50,000 employees of General Purpose Unlimited Inc. Work out VRAM and KV cache, replace Kevin's Ollama box with continuous batching, fit 35 kW of servers into three 12 kW racks, fill the nights to beat cloud rental, build a stack that survives a week of incidents, give AI agents a model that finishes its tasks, then defend every dollar in front of Régis, Counsel Bérubé and the CEO. Built on October 16, 2026 with Claude Opus 5.5
  • 🧑‍💻 Ship at any price A serious game about a year-long shift to agentic software development at General Purpose Unlimited Inc.: 21 developers in an open-plan office, seven business lines, and you tuning agent autonomy, parallel sessions, code review, tests, skills and MCP servers, data governance and security. Watch Nadia's review queue pile up, cognitive debt fog the desks, the token bill worry Régis and the lethal trifecta light up in Procurement, then defend your choices before the executive committee. Built on October 17, 2026 with Claude Opus 5.5
