I don't write reports about
what you should build.
I build it.
Infrastructure architect and AI systems builder. I design and ship production systems across the full stack: data pipelines, automation, AI orchestration, and edge infrastructure. Available for consulting, fractional, and contract work.

What I Build
Not prototypes. Production systems with proper testing, migrations, observability, and real operational burden.
Data Infrastructure
PostgreSQL with proper role hierarchy, 227 migrations, schema isolation for sensitive data, and query performance that matters (27,500x optimization on one pipeline alone).
AI Orchestration
Multi-agent systems with parallel dispatch, result contracts, and context budget management. Custom MCP proxy infrastructure with OAuth 2.1. Not "uses ChatGPT."
Automation Pipelines
76 automated workflows across email, calendar, health, voice, and system monitoring. 446K messages processed across 6 platforms.
Edge Infrastructure
Cloudflare Workers at the edge, Caddy + Authelia for auth and SSO, 5-network Docker segmentation, encrypted offsite backups. Full vertical stack, every layer understood.
Voice Pipelines
Wake word to spoken response in under 2 seconds on local hardware. Local Whisper, custom TTS, satellite devices, Home Assistant integration.
Privacy-First Architecture
Three-tier data classification with real enforcement: database roles, schema isolation, separate processing paths. Not privacy theater.
How I Work
The methodology is as important as the output. These aren't principles on a slide deck. They're how the system was actually built.
Infrastructure as code, always
Every migration is numbered and tracked. Every config is versioned. No snowflake servers, no undocumented changes. If it's not in git, it doesn't exist.
AI as a force multiplier, not a crutch
Built a Director Model for multi-agent orchestration: parallel dispatch, result contracts, context budget management. Understands the tooling deeply enough to build infrastructure on top of it.
Test coverage that earns its keep
1,593 tests across API, web, auth, workers, and webhooks. Tests that catch real bugs, not tests that check whether functions return something.
The System
chris-os is a personal infrastructure monorepo that treats a digital life as an operating system. It's the primary portfolio piece: production infrastructure built and operated solo, demonstrating what one engineer with the right methodology can ship.
Compute
Raspberry Pi 5, AMD GPU node
Database
PostgreSQL, 5 roles, 227 migrations
Automation
n8n, 76 workflows
AI
MCP agents, Ollama, voice pipeline
Edge
Cloudflare Pages, Workers, R2
Auth
Caddy + Authelia SSO
Available for work
Consulting, fractional infrastructure architect, or contract. If you need someone who can design and build the system, not just advise on it, let's talk.
