Bruno Hart.

Product engineer. I care about how innovation and well-crafted platforms improve people’s lives.

  1. 01 Cinema Ops Platform A governed data platform: idempotent bronze, watermarked reads, a gold star schema, and agent tools that structurally cannot return a person. 2026
  2. 02 Turnaround The showtime week as a constraint problem: CP-SAT builds it, unsat cores explain a no, and a checker that never imports the solver proves it again. 2026
  3. 03 The Junction Who owns the sale when an AI agent books: a thesis on merchants of record and group payment, with its forecasts frozen before the results. 2026
  4. 04 CHANGEOVER An open protocol for agentic booking. Seats held for a stated window, then handed to the cinema’s own checkout. 2026
  5. 05 Theatrical Typed API contracts in TypeScript, C# and Python, and an event bridge that turns snapshot APIs into signed events. On npm, NuGet and PyPI. 2026
  6. 06 Telecine A broadcast network with no server. The schedule is one file, and every receiver resolves it from a clock. 2026
  7. 07 Stub The whole cinema night, booked at the cinema’s own checkout. Money shown only as read; friends matched without the server learning the film. 2026
Everything, on a shelf
