Engineering Documentation RAG for Developer Onboarding

Unified RAG over API docs, architecture wikis, and runbooks to accelerate developer onboarding.

Founder note: this is written to be practical. We focus on what we learned in delivery, what changed for the team, and what results held up after rollout.

The Real Problem

1. New engineers took 6 weeks to become productive

2. Internal Slack questions repeated the same topics

3. Docs were stale and duplicated across tools

4. API references lacked contextual examples
