Software that survives reality.
I build Postgres-native systems for operational software, AI-native products, and products that range from online-first flows to field-grade offline queues. Designed to stay reliable, understandable, and maintainable long after launch day.
Fewer moving parts. Better systems.

The QR opens the door. The video was already inside.
Scan a QR on a box and a pre-rendered video plays as an AR overlay on the packaging itself. TypeScript, Supabase, and Postgres keep the link between QR, customer, and video correct every single time.

Recent notes
All notesThe rat race optimizes for visibility, not value
Most people don't wake up wanting to run a rat race. It happens slowly. You start comparing. You see what others have. You notice what gets praised, promoted, and rewarded. And without deciding it consciously, you start chasing the same signals.
I read Can't Hurt Me. I applied it wrong.
After reading Can't Hurt Me, I translated the idea into a system. My days became tight. Running early. Training. Cold plunge. Deep work blocks. Everything had a place. Nothing was accidental. But I misunderstood what Goggins was teaching.
What changes when speed is no longer the goal
I learned to program by moving fast. For a long time, speed was how I solved problems, learned new things, and got results. In group settings, that same speed started to have side effects.
