Reference checks

Checks that start, chase and close themselves.

The problem

After an old script-and-forms setup was switched off, the ops team started every reference check by hand. They emailed every former manager, read every reply and raised every follow-up by hand.

What I built

Stack: Node.js, BullMQ, Redis, AWS SES, AWS Bedrock, React.

Your version: Replies pile up in a shared inbox?

Queued follow-ups and an LLM that reads each reply and routes it; unsure ones go to a person.
