AI got me 60% there. Landing pages, dashboards, login systems all fine in theory. But real users broke everything:
Stripe payments failing randomly.
Database queries choking at 1,000+ users.
User sessions logging out unexpectedly.
Billing logic causing chaos.
AI could suggest fixes, but had zero clue about production realities. The turning point? Becoming a smarter AI supervisor: testing flows with real users, learning enough about databases and payments to know when AI code would actually survive in the wild.
Still using AI for 90% of development, but now Humanizer works with real users and real money without blowing up.
