Driving Innovation and accelerating growth through AI-Augmented Tech Leadership.
I'm Sébastien, aka Plopix, I live in California, and I come from France. I am a passionate technologist, architect, and problem-solver who has gone all-in on AI-augmented development. With a deep focus on scalability, performance, and system architecture, I build and orchestrate agentic workflows that multiply engineering output — combining agents, custom skills, MCP servers, and CLI tools to push the boundaries of what a team can ship.
This is my space to share my experience, projects, and thoughts on AI-driven engineering and the ever-evolving tech landscape. Welcome!

AI Workflow & Tooling
$ orchestrate --agents x35
CMUX managing shells · custom RALPH loop orchestrated via a custom Bun binary
All agents running in parallel...
Custom Skills
Authored agent skills like a /write-a-prd that generates structured
PRD.json file for automated
implementation.
MCP Servers & CLI Tools
Remote MCP servers to extend agent capabilities and CLI tools to streamline agentic workflows.
Plugins
Custom notification plugins that alert me when agents need attention, complete tasks, or hit blockers.
Git Worktree Integration
Agents work in isolated Git worktrees, enabling parallel development without branch conflicts.
Operating as an AI-augmented engineering team —
shipping faster, with higher quality, across more fronts.
