Auditing AI-Built Products: The 6 Pillars of Production Readiness

AI tools can generate functional code, but they lack the architectural foresight to ensure security, scalability, and reliability. Before shipping, you must manually audit your project across six critical domains to avoid catastrophic failure.

Building Deterministic Infrastructure for Non-Deterministic AI Agents

To move AI agents from demos to production, engineers must shift focus from prompt engineering to building a robust 'agent control plane' that enforces determinism, safety, and resource governance over stochastic model outputs.

Moving From Raw Logs to Observability Narratives

Logging is not the same as visibility. To debug production failures effectively, you must move beyond isolated log lines and implement request-based tracing that tells a coherent story of every execution.
