Data Analytics Engineer
Description
- Built production-grade Snowflake stored procedures to transform multi-million-row patient-level marketing interaction data into an analytical star schema for campaign attribution and performance reporting.
- Owned 4–5 analytical tables and reporting views, partnering with senior engineers and product stakeholders to finalize schema design after EDA and business-logic review.
- Wrote 8–10 parameterized stored procedures with logging-table integration and custom exception handling; an early PR became the template used by the rest of the team.
- Implemented a 400-line CTE-driven transformation pipeline, reducing reporting-scale tables from millions of rows into BI-oriented aggregates.
- Built 4 Power BI dashboards directly and contributed to a 14-dashboard reporting ecosystem supporting in-house marketing analytics.
- Developed Azure DevOps pipeline automation for ordered SQL deployment across environments, saving ~60 hours/month across a 5-developer team.
- Augmented an internal ETL migration framework using Azure Data Factory, adding new pipelines and transformations across Snowflake, Oracle, Azure SQL, and Azure Blob Storage at 10M+ row scale.
- Implemented secure ETL patterns using Azure Key Vault-backed secret resolution and post-migration SQL validation checks.
