About

I am a Data Engineer specializing in building scalable, high-performance data pipelines and distributed processing systems. At Walmart Global Tech, I leverage PySpark, Kafka, Azure SQL, and ETL Platform to design end-to-end ETL/ELT workflows, optimize large-volume data processing, and enhance reliability across mission-critical retail and forecasting systems. I focus on transforming complex data ecosystems into clean, automated, analytics-ready pipelines that support real-time business decision-making. With a Master’s degree in Data Analytics Engineering from George Mason University, I have a strong foundation in data modeling, warehousing, statistical analysis, and machine learning. My academic projects—including PySpark ETL pipelines, Airflow-based workflow orchestration, and applied ML systems—strengthened my expertise in both data engineering and decision science. I’m passionate about connecting advanced data systems with actionable insights that drive measurable impact. Earlier in my career, I contributed to backend automation and ETL development at UCode Technologies LLC, and supported SAP Security and governance initiatives at Accenture, giving me experience across engineering, analytics, and enterprise-scale technology environments. I bring a blend of technical depth, problem-solving skills, and cross-functional collaboration experience, and I’m motivated by building reliable, efficient, and intelligent data solutions that help organizations operate smarter and faster.
