Cross-source reconciliation: lead the wholesale sell-out pipeline (Snowflake + dbt) reconciling retailer sell-out data against internal sell-in figures across wholesalers on multiple continents — heterogeneous exports, no shared entity IDs, and numbers that do not agree out of the box.

Marketing attribution & MMM: lead implementation of performance-marketing metrics and media-mix modelling, attributing offline retail sales uplift to specific campaigns.

Summary

Analytics engineer with 7+ years building data platforms from the ground up and turning fragmented, disagreeing source systems into a single trustworthy picture of the business. Deep hands-on experience in Snowflake/BigQuery + dbt + Airflow warehouse design, entity resolution and reconciliation across heterogeneous sources, and financial and revenue attribution — including two years in retail brokerage, where reconciliation errors are regulatory problems, not reporting ones. Comfortable owning architectural decisions end to end, writing them down, and leading small teams through ambiguous integration work where the rules aren't documented and the data fights back.
