CLIENTNone — personal project

Understand in 30 seconds

From conversation to action, under supervision.

An inbound message is normalized and stored. Rules and a model classify it. The agent can retrieve approved knowledge, continue a commercial conversation or prepare an appointment. Complaints, refunds and sensitive situations create a human task.

Asteria is a personal prototype using a fictional company and fictional data. It is not a customer-service system deployed in production. Security, monitoring, failure recovery and load testing would need strengthening before real-world use.
