Design Systems for Startups: How I Built Mine Backwards
I built my design system backwards: tokens first, components never. A CLS bug taught me the cost of skipping tokens. I stopped debating when to invest.
Design & UXWriting
Thoughts on design, development, AI infrastructure, and building products.
Vibe 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 & 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 & TechnologyColor 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 & UXThe Pathless Path: Leaving a 12-Year VP Role to Build
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 & GrowthCompounding 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 & TechnologyMental Compound Interest: Cross-Domain Knowledge in Practice
Design + engineering + AI produced tools none of those skills alone could build. An interactive calculator and the cross-domain advantage in practice.
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.
Career & GrowthType Scales: How I Chose 13 Steps and Why the Ratio Matters
My site uses a 13-step type scale from 12px to 80px. How I chose the ratio, why system fonts outperform custom fonts, and what the squint test reveals.
Design & UXStartup Validation Stack: What 12 Projects Taught Me
I validated 12 projects in 9 months. Some followed the framework. Some skipped steps. The difference in outcomes taught me which evidence actually matters.
Career & GrowthBuilding 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 + 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.
