PRD-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.

Thoughts on design, development, AI infrastructure, and building products.
Building Design Teams That Ship: What 12 Years at ZipRecruiter Taught Me
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: What 30 Sessions of Combined Usage Taught Me
I tracked 30 development sessions using Claude Code and Cursor together. The data shows where each tool wins and where the combination fails.
AI DevelopmentCompounding Engineering: How My Codebase Accelerates Instead of Decaying
Most codebases slow down as they grow. Mine accelerates. The difference: 95 hooks, 44 skills, and 14 configs that make each new feature cheaper than the last.
AI & TechnologyAI Theater: Why 90% of Companies 'Use AI' But Only 23% Create 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 & TechnologyDesign Systems for Startups: How I Built Mine Backwards
I built my design system backwards — tokens first, components never. After a CLS bug taught me the cost of skipping tokens, I stopped debating when to invest.
Design & UXColor 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 & UXBeauty and Brutalism: How I Designed blakecrosley.com at the Intersection
I built my site at the intersection of beauty and brutalism: structural honesty with precise typography on absolute black.
Design & UXBuilding 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 & 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 & ProductivityCritical 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 Ralph Loop: How I Run Autonomous AI Agents Overnight
I built an autonomous agent system with stop hooks, spawn budgets, and filesystem memory. Here are the failures and what actually ships code.
