About Mary Mallavarapu

I\'m a Data Engineer with experience to transforming complex data challenges into high-impact, cloud-native solutions. What gets me up in the morning? Architecting robust, scalable pipelines that can handle terabytes of data daily and seeing that work translate into faster risk analysis or improved BI query performance.My sweet spot is in the multi-cloud world. I\'m an expert at integrating and optimizing the entire data lifecycle across GCP (BigQuery, Cloud Dataproc) and AWS (S3, EMR, Redshift). Whether it\'s orchestrating complex ETL/ELT workflows with Airflow/Cloud Composer, driving cloud migrations that cut infrastructure costs by 25%, or building low-latency data access services with Java, I thrive on engineering efficiency.I’m particularly strong in the Hadoop Ecosystem, with deep expertise in Apache Spark (PySpark/Scala), Kafka, and modern data platforms like Databricks and Snowflake. I don\'t just build pipelines; I focus on data governance, code quality, and implementing DevOps practices (Terraform, Docker) to ensure the platforms are reliable, secure, and ready for the next big challenge in finance, telecom, or healthcareLet\'s connect if you\'re building the future of data and need an engineer who can move seamlessly from design to high-performance execution!
