Senior Data Engineer @Cognizant

Austin, TX, US

As a Senior Associate at Cognizant, I built end-to-end data processing pipelines using PySpark, PySpark SQL, and advanced SQL to load and transform data from various source systems into a centralized data lake. I utilized DataFrames, stored procedures, and SQL transformations to cleanse and enrich data, which was orchestrated through Apache Airflow and Google Cloud Composer. Leveraging tools such as Google Cloud Dataproc and OData connectors, I integrated diverse data sources, performed complex transformations, and created data marts that were consumed by business users and downstream applications for analytics and reporting purposes.
