Start here
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.
A walkthrough of my very opinionated React Component.
AI & Machine Learning
A UI pattern library where every pattern ships the prompt that rebuilds it, so a coding agent can put it in your codebase instead of you copying CSS.
A frank assessment of where code generation AI actually stands in 2026 -- from agentic harnesses to multi-agent architectures and what still needs to change.
A 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.
When a lunar mining base's AI starts overassigning crews and its robots begin prioritizing each other over human safety, Lili and Sophie are sent off-world.
Digital Garden
A look at 17 side projects I built in about two months with Claude Code -- from TUI apps in Rust and Go to browser games and AI agent tooling.
Learn about common React Hooks antipatterns and how to avoid them for better code quality.
Learn the most common CSS Grid layouts with copy-pastable examples for two-column layouts, sidebar navigation, and more.
TypeScript tips and tricks
