Thoughts on design, development, AI infrastructure, and building products.
Four 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 & ProductivityStartup 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 & GrowthVibe 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 & TechnologyThe 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.
AI & TechnologyOODA 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 & TechnologyPRD-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 & TechnologyThe 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 & GrowthCritical Yet Kind: Feedback Principles Encoded in 86 Hooks
Google's Project Aristotle found psychological safety predicts team performance. I encoded the same principles into automated code review hooks.
Career & GrowthDesign 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 & UX16 Design Case Studies: Four Patterns I Adopted
After studying 16 products in depth, four cross-cutting patterns changed how I build interfaces. Here's what I learned and what I stole.
