I gave Claude Code our entire codebase. Our customers noticed. | Al Chen (Galileo)

Al Chen is a field engineer at Galileo, an observability platform for AI applications, where he works on the front lines with enterprise customers asking highly technical questions. Despite never having held an engineering role, Al has built a system using Claude Code to query Galileo’s 15 separate repositories, combine that with Confluence documentation and customer-specific quirks, and deliver hyper-personalized answers that would otherwise require constant engineering support.

What you’ll learn:

1. How to use Claude Code to query multiple repositories simultaneously for customer support
2. Why code is often a better source of truth than documentation
3. How to combine repository context with Confluence and Slack using MCPs
4. The “customer quirks” system that creates hyper-personalized deployment guides
5. How to build virtuous loops that turn single customer questions into scalable knowledge
6. Why information organization matters less in the AI era
7. A simple 16-line script (written by Claude Code) that pulls the latest main branch across all your repositories to keep your context current
8. How to reduce engineering interruptions to near-zero by empowering customer-facing teams to query the codebase directly
