Featured project
Escadron & Cockpit
Status: Personal setup · used daily
Runs on my own machines, server and agents: built for one person, not offered to others.
A self-hosted fleet of AI agents for software engineering, and the workstation to drive it.
Escadron · The review loop
- Orchestrator Receives a task and writes a scoped brief.
- Coding agent Implements it on a branch and opens a pull request. Its engine is interchangeable: Escadron is not tied to one model or tool.
- Tour de Contrôle · independent reviewer Never reviews its own work. Re-runs the tests, mutates the code to prove the tests catch regressions, and gives a verdict.
- Human Merges.
Cockpit
The desktop web workstation to drive the fleet (missions, reviews, agents, infrastructure) in one screen. Passkey login.
Boîte Noire
Shared memory, an MCP server, that records every decision and verdict.
Hangar
Mines finished cycles and proposes improvements, applied only after human approval.
Next: the Harness
Status: In design
The rules, workflow and tooling distilled from daily use of Escadron & Cockpit, packaged so that a team can use them. Unlike Escadron and Cockpit, it is meant to be shared.
First piloted with a development team, to get feedback.
Tools planned for sharing
Shared memory between agents
Planned: one memory for the team's agents.
Several Tours de Contrôle
Planned: several independent reviewers for a team.

Testimonials
-
Kévin carried out a complete audit of Docstring's compliance, covering both the legal documentation and cybersecurity. The audit was very precise and thorough, and Kévin was able to work almost autonomously thanks to his skills on both the legal and the technical side. Very satisfied, then, with the overall work he delivered 🙂
Docstring Translated from French -
I highly recommend Kévin. We were pleasantly surprised by his management and organisational skills. He carried out his work efficiently, with clear communication and flexibility.
Founder of Hyping (Minecraft server) Translated from French -
