Sales data pipeline and reporting dashboard

Harbor Analytics needs a data pipeline for a logistics client: ingest daily sales exports (CSV over SFTP), load them into PostgreSQL, model the data and build a reporting dashboard the client's ops team can use. The dashboard should cover revenue by lane, on-time delivery rates and weekly trends. We are open to your tooling suggestions for the dashboard layer as long as it is maintainable and self-hosted. Documentation and a handover call are part of the scope. Data volumes are modest, low millions of rows.
