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.
AI DevelopmentWriting
Thoughts on design, development, AI infrastructure, and building products.
Color Science for Interfaces: Building a Zero-Color Site
I built a site with no colors — just white on absolute black with four opacity layers. Here's the color science that made the decision work.
Design & UXVibe Coding vs. Engineering: Where I Draw the Line
I use Claude Code daily with 86 hooks and a full quality gate system. Here's where I vibe code, where I engineer, and why the boundary matters.
AI & TechnologyBuilding Design Teams That Ship: 12 Years of Evidence
After 12 years leading product design at ZipRecruiter, I learned which team structures ship and which polish endlessly. The patterns surprised me.
Design & UXClaude 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 DevelopmentOODA Loop Prompt Engineering: What Five Failures Taught Me
Five prompt failures taught me that structured observation beats clever wording. Boyd's OODA loop maps directly to my daily prompt engineering workflow.
AI & TechnologyContext Window Management: 50 Sessions of Data
I measured token consumption across 50 Claude Code sessions. Context exhaustion degrades output before you notice. Here are the patterns that fix it.
AI DevelopmentAI Theater: Why Only 23% of Companies Create Real Value
McKinsey found 90% of companies claim AI adoption but only 23% scale beyond pilots. I've witnessed three flavors of AI theater and practiced one myself.
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 & TechnologyLLM 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 & TechnologyDecision Timing: The 15x Cost of a Bad Database Choice
I measured the cost of a database decision across three systems. Migration cost grew 15x in three years. A framework for when to decide fast vs slow.
Systems & ProductivityCritical Yet Kind: Feedback Principles Encoded in 86 Hooks
Google's Project Aristotle found psychological safety predicts team performance. I encoded the same principles into automated code review hooks.
