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 & ProductivityWriting
Thoughts on design, development, AI infrastructure, and building products.
Mental Compound Interest: How Cross-Domain Knowledge Built My Best Tools
Design + engineering + AI produced tools none of those skills alone could build. An interactive calculator and the cross-domain advantage in practice.
Systems & ProductivityThe 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 & ProductivityThe 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 & TechnologyClaude 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 DevelopmentBuilding 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 & UXThe Design Career That Survives AI
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 & UXThe Pathless Path: How I Left a 12-Year VP Role to Build 12 Projects
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 & GrowthContext Window Management: What 50 Sessions Taught Me About AI Development
I measured token consumption across 50 Claude Code sessions. Context exhaustion degrades output before you notice. Here are the patterns that fix it.
AI DevelopmentThe 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 & 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 & TechnologyThe Startup Validation Stack: What 12 Projects Taught Me About Evidence
I validated 12 projects in 9 months. Some followed the framework. Some skipped steps. The difference in outcomes taught me which evidence actually matters.
