Production notes on AI engineering

Hi, I'm Pawel

My name is Pawel Twardziak - I'm a software developer with 14 years of experience. Official LangChain Expert and an active contributor to LangChain repositories. On the official LangChain forum, I help solve technical problems and support the community.

Since 2024, I've been focusing on AI - primarily on AI-native programming, where the developer acts as a director who takes responsibility for the outcome, and on building agents that run in production environments.

On LangHug.blog I write practical guides, deep technical dives, and research notes that help developers build better AI-powered systems.
