Commands, Skills, Subagents, Rules: What I Learned Organizing 139 Extensions
Claude Code offers four extension types. After building 95 hooks, 44 skills, and dozens of commands, I learned which abstraction fits which problem.

Thoughts on design, development, AI infrastructure, and building products.
The Design Career That Survives AI
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 & UXThe OODA Loop for 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 the prompt engineering workflow I use daily.
AI & TechnologyThe Pathless Path: How I Left a 12-Year VP Role to Build 12 Projects
I left VP of Product Design at ZipRecruiter after 12 years to build independently. No plan, no destination, just curiosity and a financial runway.
Career & GrowthVibe 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 & TechnologyContext Window Management: What 50 Sessions Taught Me About AI Development
I measured token consumption across 50 Claude Code sessions. Context exhaustion degrades output before you notice. Here are the patterns that fix it.
AI DevelopmentHow LLMs See Text: What My i18n System Taught Me About Token Economics
Translating my site into 6 languages revealed that Korean costs 2.8x more tokens than English for identical content. The interactive visualizer below shows why.
AI & TechnologyType Scales: How I Chose 13 Steps and Why the Ratio Matters
My site uses a 13-step type scale from 12px to 80px. Here's how I chose the ratio, why system fonts outperform custom fonts, and what the squint test reveals.
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 DevelopmentMental Compound Interest: How Cross-Domain Knowledge Built My Best Tools
Design + engineering + AI produced tools none of those skills alone could build. An interactive calculator and the cross-domain advantage in practice.
Systems & Productivity16 Design Case Studies: The Four Patterns I Adopted Into My Own Work
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.
