Unified Data Infrastructure Architecture

Central Data Warehouse

Consolidates operational data into cloud data platforms (Snowflake, BigQuery, Databricks) using automated ETL pipelines (Fivetran, Airbyte).

Reverse ETL & Operational Analytics

Pushes aggregated warehouse insights back into frontline tools (Salesforce, Gainsight) via Reverse ETL platforms (Census, Hightouch) to surface user usage metrics directly to customer-facing teams.
