Building CollectYourCards With AI
- Jeff built CollectYourCards.com during COVID after moving from spreadsheets to a custom app with AI assistance.
- He used Claude to generate code and iterate features while learning how to manage AI-driven development.
Observability Replaces Line-by-Line Review
- You cannot review thousands of AI-generated lines manually so rely on tests and observability to validate behavior.
- Instrumentation and metrics become your trust mechanism when you can't audit every line.
Use GitHub Issues As The Backlog
- Use GitHub issues as a persistent backlog to externalize AI context and preserve feature definitions.
- Create issues so AI-generated plans and edge-case thinking are stored and prioritized for later work.
