PRD-Driven Development: How I Use 30+ PRDs to Ship with AI Agents
I've written 30+ PRDs for AI agent tasks. Here's where PRD-driven development works, where it fails, and how my template evolved over 6 months.

Thoughts on design, development, AI infrastructure, and building products.
Compounding Engineering: Why My Codebase Accelerates
Most codebases slow down as they grow. Mine accelerates. 95 hooks, 44 skills, and 14 configs make each feature cheaper than the last.
AI & TechnologyBrutalist Web Design Meets Beauty: My Site's Approach
I built my site at the intersection of beauty and brutalism: structural honesty, precise typography, and four opacity tiers on absolute black. No colors needed.
Design & UXClaude Code Extensions: Organizing 139 Skills and Hooks
Claude Code offers four extension types. After building 95 hooks, 44 skills, and dozens of commands, I learned which abstraction fits which problem.
AI DevelopmentClaude Code + Cursor: 30 Sessions of Combined Use
I tracked 30 development sessions using Claude Code and Cursor together. The data shows where each tool wins and where the combination fails.
AI DevelopmentLLM Tokenization: Why Korean Costs 2.8x More Than English
Translating my site into 6 languages revealed that Korean costs 2.8x more tokens than English for identical content. An interactive visualizer shows why.
AI & TechnologyBuilding AI Systems: From RAG to Agents
I built a 3,500-line agent system with 86 hooks and consensus validation. Here's what I learned about RAG, fine-tuning, and agent orchestration.
AI & TechnologyClaude Code Hooks: Why Each of My 95 Hooks Exists
I built 95 hooks for Claude Code. Each one exists because something went wrong. Here are the origin stories and the architecture that emerged.
AI DevelopmentDesign Careers That Survive AI: Judgment Over Tools
After 12 years as VP of Product Design, I watched three paradigm shifts. The skills that survived every one are the same skills AI can't replace.
Design & UXFour Years of Past Year Reviews: What I Actually Learned
Four years of Past Year Review data revealed which decisions compound and which drain energy. The data changed how I make career decisions.
Systems & Productivity16 Design Case Studies: Four Patterns I Adopted
After studying 16 products in depth, four cross-cutting patterns changed how I build interfaces. Here's what I learned and what I stole.
Design & UXHamming Codes: How Computers Catch Their Own Mistakes
Every time you use RAM, read a QR code, or receive data from space, Hamming codes fix errors. An interactive exploration of self-correcting math.
