Engineering & Infrastructure

Marketing analytics data originates from a wide range of platforms, including Google Ads, Meta, The Trade Desk, Campaign Manager, CRM systems, and web analytics tools. Before this data can be visualized or analyzed, it must be ingested, standardized, and prepared for reporting.

We use Snowflake as our data warehouse for data processing and storage, and Power BI as the data experience platform that makes information accessible, intuitive, and actionable for internal teams and clients alike.

We built a custom data pipeline using Python and GCP Cloud Functions to ingest data from every platform into Snowflake, using Windsor.ai for select social and organic data sources, where SQL transforms it into clean, reportable tables. Power BI connects directly to Snowflake to deliver that reporting. This approach gives us full control over data quality, lets us fix issues at the source instead of patching them downstream, and scales to handle the specific quirks of each client's platforms and campaigns. The Lewis Media data ecosystem is secure, built on validated pipelines, and adaptable to a wide range of client and business needs.
