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 & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
Claude 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 & GrowthStartup 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 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 & 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 & UXPRD-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 DevelopmentCompounding 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 & TechnologyDesign 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 & UXAI 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 & 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.
