Introduction: LangChain has emerged as the dominant framework for building production Retrieval-Augmented Generation (RAG) applications, providing abstractions for document loading, text splitting, embedding, vector storage, and retrieval chains. By late 2023, LangChain reached production maturity with improved stability, better documentation, and enterprise-ready features. After deploying LangChain-based RAG systems across multiple organizations, I’ve found that its […]

After two decades of managing cloud infrastructure across enterprises of all sizes, I’ve witnessed the evolution of Infrastructure as Code from simple shell scripts to sophisticated declarative frameworks. AWS Cloud Development Kit (CDK) represents a paradigm shift that fundamentally changes how we think about infrastructure provisioning. Rather than wrestling with YAML or JSON templates, CDK […]
Read more →LLM Observability: Tracing, Cost Tracking, and Quality Monitoring for Production AI
Introduction: You can’t improve what you can’t measure. LLM applications are notoriously difficult to debug—prompts are opaque, responses are non-deterministic, and failures often manifest as subtle quality degradation rather than crashes. Observability gives you visibility into every LLM call: what prompts were sent, what responses came back, how long it took, how much it cost, […]
