Senior Data Engineer delivering scalable data platforms, cost savings, and reliable analytics pipelines.
United StatesWhat I'm looking for
I am a Senior Data Engineer with 8+ years building scalable data platforms and analytics pipelines across travel, e-commerce, healthcare, and fintech. I specialize in designing high-throughput ETL/ELT workflows and dimensional data models to drive accurate, timely reporting.
At BCD Travel I architected Airflow orchestration and Kafka ingestion for 100+ daily pipelines, enabling sub-5-minute reporting and reducing cloud costs by 18%. At Wayfair I developed AWS ETL workflows and star-schema models that cut Redshift query runtimes by 50% for fulfillment analytics.
At Olive AI I unified claims and EHR data in BigQuery, improving pipeline reliability from 97% to 99.5% and reducing reporting inconsistencies by 35%. Earlier at Capital One I engineered Java/Spring APIs and ETL pipelines for large-scale transaction analytics, improving API response times and data availability.
I deliver reliable, performant data infrastructure, optimize costs and throughput, and partner closely with cross-functional teams to turn complex data into actionable business insights.
