Our databases weren't dead, but they weren't healthy either. And I was tired of answering the same questions. "Is this index being used?" "Why is vacuum not running?" "What version of Postgres are we on?" So I built pgdoctor - a CLI with opinionated health checks for PostgreSQL. Each check explains what it found and why it matters, but also gives you the exact command to fix it - because most engineers just want to know what to do.

It was a simple tool for a specific problem. But then our CTO picked up the pattern and built repo-doctor - same architecture, different domain. It analyses repositories for good and bad signals: Kubernetes configs, library choices, ownership files, documentation, dev setup. Each service gets a score. We collect those scores into a scoreboard visible to the whole engineering organisation, and suddenly we have a shared language to talk to product about technical health.

The architecture was simple enough to copy, the pattern was clear enough to follow, and frameworks like Bubbletea made building polished terminal interfaces surprisingly fast.
