Hi, I'm Raphael 👋

🤖 Building infrastructure for AI-assisted software delivery
🦀 Rust · TypeScript · Go | 🏢 NFON

I build local-first tools that make AI coding agents more governable, observable, and useful.

Start Here

• 🧠 sekai-chisei — a local-first Rust control plane for ontology-driven, governed agent operations: policy, budgets, audit, evaluation and routing
• ⛩️ shikigami — a local-first headless agent harness with pluggable governance adapters
• 🚀 tenkai — a local-first, constraint-based delivery control plane, with a web console in tenkai-console
• 🗄️ mikura — an object database: durable object log, object-set evaluation, property ACLs and Action writeback

Agents

• 🚧 sekisho — a governed tool gateway for AI agents (MCP): per-agent identity, token exchange, tool registry, rate limits and audit
• 🏠 rusui — a self-hosted environment plane for coding agents
• 🧰 agent-kit — shared agent skills and scripts for my repositories

Data and Engines

• 🐉 mizuchi — an Arrow-native query and transform engine in Rust, with a web console in mizuchi-console
• ⚙️ kako — a sandboxed data-transform runner for SQL and Python jobs, with receipts
• 🌉 hashi — a connector engine: OPC UA, MQTT, Modbus, historians and change data capture
• 🗺️ ezu — a live spatial engine: moving-entity index, spatial queries, geofencing events and tracks
• 📐 hinagata — a registry for classical ML models: versions, typed signatures, lineage, stages and drift monitoring
• 🛡️ kekkai — sandbox child processes on Linux from Rust: Landlock, seccomp and resource limits

Tools and Side Projects

• 🏯 bugyo — a desktop command center for parallel AI coding sessions with isolated worktrees and human-in-the-loop review
• 🔔 hibiki — an approval-gated workflow that turns real engineering work into evidence-backed posts
• 📈 quantforge — a local-first research workbench for long-term investors
• 🌌 hoshi — a real-time idle space-strategy game for the terminal, played while your coding agents work, with a web client in hoshi-web

Current Focus

• Governed and observable agent operations
• Human-in-the-loop software delivery
• Local-first developer infrastructure
• Rust-powered systems and desktop tooling

Philosophy

Build the control plane that lets agents move fast without losing human oversight.
