AIRetrieval-Augmented Generation in Production: Architecture Beyond the Demo

A weekend RAG demo is trivial. A retrieval system that stays accurate, fast, and grounded under real traffic is not. We cover chunking, hybrid retrieval, reranking, evaluation, and the freshness loop most teams skip.

IoTPredictive Maintenance That Pays: From Vibration Data to Remaining Useful Life

Most predictive-maintenance pilots produce dashboards, not savings. The difference is whether the model drives a maintenance decision and whether anyone trusts it. A grounded approach from sensors to return on investment.

EngineeringObservability for Production ML: Catching Model Decay Before Your Users Do

Standard observability tells you the service is up. It says nothing about whether the model is still right. Data drift, concept drift, and silent degradation need their own instrumentation. Here is the stack that works.

AIGuardrails, Not Gates: Governing Generative AI Without Killing Velocity

Heavy approval boards make AI safe by making it useless, and teams route around them. A paved-road approach encodes governance into the platform so the safe path is also the fast path. What that looks like in practice.
