Experience-driven notes on platform architecture, reliability, developer experience, frontend systems, and applied AI. The platform and reliability pieces come first; AI writing is kept when it contains a durable engineering idea rather than a trend summary.
Writing
Agent systems and developer experience
Claude and the New Rules of Context Engineering
Why better interfaces, scoped context, and executable references matter more than ever-expanding instruction files.
Applied AI and reliability
Evals: The Missing Engineering Layer in AI Applications
A practical argument for grading both what an agent achieves and how it uses tools, permissions, and approvals.
AI standards and governance
A Possible TC39 Moment for AI
A standards-and-governance thought experiment for increasingly capable AI systems.
Platform and developer experience
Building Frontend Platforms Instead of Pages
A practical field guide to turning repeated frontend pain into paved roads without making the platform a tax.
