Production notes on AI engineering

Hi, I'm Pawel

LangHug.blog is my blog dedicated to exploring the rapidly evolving world of AI agents, language models, and the engineering patterns that make them work in production.

I write practical guides, deep technical dives, and research notes that help developers build better AI-powered systems. I focus on clarity, accuracy, and real-world applicability.

My name is Pawel Twardziak and I am a software engineer with 14 years of experience. I am passionate about programming and AI, including building AI agents and agentic systems (agent engineering), as well as AI-assisted programming (agentic software engineering). I am an official LangChain Expert and a contributor to LangChain repositories.
