Decision 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.

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 & TechnologyBrutalist 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 & 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.
AI DevelopmentBuilding 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 & TechnologyDesign 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.
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 & UXDesign 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 & 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 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.
