— The Manifesto

I build systems that manage users, orchestrate workflows, integrate APIs, and maintain server infrastructure — with logs, guardrails, and clear metrics.

— The Three Rules

Logs.

If it ran, it left a trail. Structured, queryable, audit-ready.

Guardrails.

Retries, rate limits, kill switches. Systems fail safely, not silently.

Metrics.

You can't fix what you can't see. Every flow ships with dashboards.
