Type 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 & UXWriting
Thoughts on design, development, AI infrastructure, and building products.
The 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 my daily prompt engineering workflow.
AI & TechnologyFour Years of Past Year Reviews: What I Actually Learned
Four years of Past Year Review data revealed which decisions compound and which drain energy. The data changed how I make career decisions.
Systems & ProductivityPRD-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: How My Codebase Accelerates Instead of Decaying
Most codebases slow down as they grow. Mine accelerates. 95 hooks, 44 skills, and 14 configs make each feature cheaper than the last.
AI & TechnologyVibe 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 & TechnologyCommands, 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.
AI DevelopmentColor Science for Interface Designers: What I Learned 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 & UXCritical Yet Kind: How I Encoded Feedback Principles into 86 Hooks
Google's Project Aristotle found psychological safety predicts team performance. I encoded the same principles into automated code review hooks.
Career & GrowthThe 15x Cost of a Bad Database Decision: Lessons in Decision Timing
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 & ProductivityBuilding 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 & TechnologyHow 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. An interactive visualizer shows why.
