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.

Thoughts on design, development, AI infrastructure, and building products.
Claude 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 DevelopmentClaude 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 DevelopmentType 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 & UXBrutalist 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 & UXLLM 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 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 DevelopmentThe 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 & GrowthDecision 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 & ProductivityDesign 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 & UXOODA 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.
