Senior Data Engineer specializing in cloud-native lakehouse and analytics platforms.
United StatesWhat I'm looking for
I am a Senior Data Engineer with 7+ years designing, building, and optimizing large-scale cloud-native data platforms and lakehouse architectures across Azure, AWS, and Snowflake. I specialize in Azure Data Factory, Databricks, Apache Spark, SQL, and dbt to deliver analytics-ready datasets at scale.
At CareEvolution I engineered HIPAA-compliant lakehouse solutions, standardized clinical and claims data with PySpark and dbt, and optimized Spark and Snowflake workloads to reduce pipeline execution time by 50% while supporting 200+ business users and AI/ML initiatives. Previously, I modernized on-prem data warehouses to cloud platforms, improving reporting performance and reducing costs.
I focus on building reliable, secure, and performant ETL/ELT pipelines (batch, incremental, and streaming), implementing governance and automated quality checks, and enabling self-service BI with Power BI and Tableau to drive operational insights and predictive analytics.
