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.
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.
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.
Digital Garden
Things that grew slowly: component anatomy, CSS grids, TypeScript habits, and a two-month sprint of side projects.
View all writing →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.

Open Source
A React component library built alongside a YouTube tutorial series. Clean, reusable, well-tested code.
Photo organization TUI with video sorting support. Organizes photos into year/month/date folders. Built a TUI around the original script for a better workflow.
A dashboard and Model Context Protocol server for a project portfolio whose entire state lives in markdown files. Twenty-five zod-typed MCP tools let Claude Code read roadmaps, advance sessions, and work QA queues without anyone opening the UI. No database: the files are the source of truth, and git is the audit log.
A collection of personal prompts and utility prompts packaged as SKILLs for Claude Code. Easily installable via npx.
A TUI for embedding skills into a CLAUDE.md file so Claude has a higher chance of picking them up.
A collection of proverbs from the programmer. Went viral with hundreds of stars and contributions from the community.
Personal VIM/Neovim configuration that ended up featured in the video game Watch Dogs 2.
A Babel plugin that adds JavaScript namespace support for cleaner code organization.
A file-based content management system built on Node.js for simple, flat-file websites.
