Sam Keen will elevate your AI-assisted development

I spent 25+ years as a software architect before going full-time on AI research and teaching. I found AI too exciting to keep as a side interest, so I made it the whole job.

AI tooling changes fast enough that keeping up takes real commitment. I co-founded Portland AI Engineers, publish the Altered Craft newsletter, and wrote a book on clean software architecture. All to help close the gap between what's possible and what people actually do.

I use AI development tools daily as my primary workflow, and I enjoy helping others put what I've learned into practice. I teach the systems I work in every day.

Context Engineering for Claude Code

Strong content. The Context Ladder framework gives you a clear way to think about where different instructions should live, from CLAUDE.md files up through skills and hooks, and I walked out realizing a few of my own rules were sitting on the wrong rung. The Anchored Interview pattern for building skills was the other standout, and the companion article he wrote on it is really good. Sam is knowledgeable and generous with his time. He paused for questions throughout, gave me specific guidance on managing context across multiple devices, and shared his office hours calendar so the help continues after the session. Know the format going in though. This is a lecture with slides and screen shared demos, not a hands-on workshop, and the templates and demo repo come afterward rather than during. The knowledge is shared but the implementation is on you to do async, on your own time.

Context Engineering for Claude Code

Excellent info and explanations about the various aspects of Claude Code context, hooks, and skills. I was able to make some enhancements to my current Claude Code workflow the same day and share some tips with my team at work. Highly recommend this course for new or experienced users of Claude Code.
