I’m a results-driven Data Engineer with proven experience designing and optimizing large-scale data pipelines using Google BigQuery, SQL Server, and Apache Airflow. With a strong foundation in advanced SQL and modular ETL design, I’ve led high-impact projects that reduced processing time and resource usage by implementing batching, query tuning, and efficient Airflow orchestration. I’ve successfully automated data flows from cloud to on-premise systems, moving millions of records from BigQuery to SQL Server. while ensuring data quality, performance, and reliability. I thrive in cross-functional environments and take pride in building production-ready, scalable, and cost-efficient data solutions that empower smarter decision-making. Always learning, always optimizing. Let’s connect if you’re looking for someone who can turn complex data challenges into elegant solutions.
