Internal docs that the new engineer can actually find.

The Slack channel #eng-help was the de facto answer system, because the canonical search across systems didn’t work. New engineers asked questions whose answers were technically documented somewhere — they just couldn’t find them.

Kendra’s pre-built connectors ingested Notion, GitHub, Backstage, and the Confluence archive. A small Lambda fronted the Kendra index with a Cognito-authenticated UI that engineers could open from any browser. Kendra’s relevance ML tunes itself from click-through signals over time.

Time-to-find-an-answer dropped 68% in the new-hire survey three months after rollout. Support queries in #eng-help dropped 42% — the questions still come, but they’re harder ones that genuinely need a human. The first 58% of "where is this documented?" answered itself.
