Built a SaaS with AI and almost got destroyed by production problems

Been building a tool that turns AI text into natural human writing with basically zero technical background.

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.
