About Julian Walder
Applied AI and builder. I design and ship AI-powered products — and this whole site is one of them.
I build practical systems with large language models — from retrieval pipelines and autonomous agents to the kind of end-to-end automation that runs this very website. I care about shipping things that are accurate, useful, and maintainable.
This site is a living demo: the blog writes and reviews itself, the newsletter sends itself, and the assistant in the corner can tell you about my work. Explore the portfolio to see how I frame each project — problem, solution, and the stack that made it work.
