After 20 years in this industry, I’ve seen Production Model Deployment Patterns evolve from [past state] to [current state]. The fundamentals haven’t changed, but the implementation details have. Let me share what I’ve learned. The Fundamentals Understanding the fundamentals is crucial. Many people skip this and jump to implementation, which leads to problems later. How… Continue reading

Building Production RAG Applications with LangChain: From Document Ingestion to Conversational AI
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… Continue reading
Python 3.12 Unveiled: Type Parameter Syntax, F-String Enhancements, and the Path to True Parallelism
Introduction: Python 3.12, released in October 2023, delivers significant improvements to error messages, f-string capabilities, and type system features. This release introduces per-interpreter GIL as an experimental feature, paving the way for true parallelism in future versions. After adopting Python 3.12 in production data pipelines, I’ve found the improved error messages dramatically reduce debugging time… Continue reading
