Production AI Agents

I build the tools, guardrails, and integrations that move AI models beyond chat and into production — where mistakes are expensive.

  • 450+ production PRs merged by tech leads in under 4 months (>83% human acceptance rate) across 10 repos under a strict 2-PR limit.
  • 9 AI agents in production — one central orchestrator and eight specialized profiles across engineering and operations.
  • Self-hosted on Hermes — the open-source agent runtime by Nous Research.

The agents

Central Orchestrator

Control plane for the fleet. Runs daily cognitive health audits, enforces skill integrity, and maintains strict security isolation between domains.

Engineering & FinOps

Resolves GitHub issues, runs local test suites, and opens PRs across 10 production repositories under human review while pruning AWS cloud spend.

Business Operations

Seven dedicated profiles across sales, CS, support, marketing, projects, intelligence, and leadership, handling 3,000+ human messages monthly.

Guardrails that make delegation real

Production repositories need more than a good model. This is what had to exist first.

01 // Human review

No direct pushes, ever

Capped at 2 open PRs per repo so the team never gets overwhelmed. The agent runs local tests, CI must pass green, and an engineer always reviews before merge.

02 // Real scope

Real problems, zero busywork

No cosmetic churn or whitespace refactoring. The agent tackles actual backlog issues: async race conditions, component migrations, and end-to-end test suites.

03 // Isolation

Each agent in its own lane

Each profile runs in an isolated sandbox with its own tools and procedures. The sales agent never touches source code, and context never bleeds across domains.

04 // Cost & safety

Scripts before LLMs

Anything that can be solved with Bash, Python, or Git never calls an LLM. This prevents hallucinations, runs quiet security checks, and keeps token spend strictly under $140/mo per profile.

How it's built

Self-hosted end to end — the agent runtime, SQLite state, and every integration run on our own infrastructure, decoupled from inference providers. Swapping the model is a config change; the guardrails and review process stay the same.
