After 12 Failed Deployments, I Built This Pre-Production Checklist. It Saved Us $340K.

Deployment 12. Almost Got Me Fired. Then I Got Angry and Built a System That Actually Works.

Friday, 4:47 PM.

I hit deploy.

By 5:15 PM, the CEO was in my DMs.

By 6:00 PM, we’d lost $28,000 in failed transactions.

By Monday morning, I was explaining to the board why our “production-ready” feature had taken down the entire payment system.

That was deployment #12.

And I was fucking done.
