The Cloud Codex is an independent publication launched in 2023 by Michael Tuszynski: field notes on building with AI agents — the harness around the model, what the tokens actually cost, and the platform engineering that keeps it production-grade. Written from what he ships daily — "not the sanitized conference-talk version — the real version."
Who's writing
Mike has spent 25 years shipping production systems: a coder at investment firms, an engineering leader at a streaming platform, six years as a Solutions Architect at AWS, and currently Principal Architect at Presidio. This site exists to provide trustworthy technical content from someone accountable for production systems — "people who've been paged at 3 AM and had to explain outages to executives."
