What I'm looking for

I seek senior data engineering roles building scalable, secure cloud data platforms, emphasizing governance, automation, and cross-functional impact.

I am a Senior Data Engineer with over nine years building scalable ETL pipelines, cloud-native data platforms, and analytics warehouses to enable data-driven decisions. I specialize in Python, Spark, Airflow, Snowflake, Redshift, and cloud solutions (AWS, GCP, Azure), and I deliver robust, compliant systems for high-volume, regulated environments.

I have led real-time architectures using Kafka and dbt, implemented automated validation and CI/CD practices, and deployed machine learning models into production that improved outcomes such as recovery effectiveness and churn detection. I prioritize data governance, security, and cross-functional collaboration to drive measurable business impact while maintaining operational reliability.
