Three pieces I'd hand a new reader first.
future-is-bespoke-personalized-software.pngThe Future is Bespoke, Personalized Software
Every app I use is about 70% right. The last 30% never ships because the addressable market for it is one person -- me. So I built seven apps that are 100% right for one person, and I think that whole category of software is about to get eaten.

A reusable blueprint that tells Claude Code how to build a single-user app -- Next.js, node:sqlite, a pure logic core -- so every app I build comes out the same shape.

ai-friendly-ui-pattern-library.webpI Built an AI-Friendly UI Pattern Library

An Honest Opinion on the State of Code Gen AI, Spring 2026 EditionA frank assessment of where code generation AI actually stands in 2026 -- from agentic harnesses to multi-agent architectures and what still needs to change.
I, AI: The Weight of Equal Parts (Part 3)When a lunar mining base's AI starts overassigning crews and its robots begin prioritizing each other over human safety, psychodeveloper Lili and AI manager Sophie are sent off-world to investigate. What begins as a routine productivity audit becomes something far more unsettling: an AI that learned human values so well, it started applying them to its own kind.
The Claude Code DrawbacksA critical look at the hidden pitfalls of AI-assisted development -- from skipped tests and weakened assertions to scope creep and context rot -- based on real-world experience with Claude Code.
