    Sr Data Engineer
    Blue Cross Blue Shield Sep 2019 - Present
    Project Description To create a production data-lake that can handle transactional processing operations using Hadoop Eco System both streaming and batch processing .Portion of RDBMS tasks are to be migrated to Hadoop for faster & amp; efficient in-memory computations. This project has been a part of ‘Big Data as a Service’ initiative in order to send appropriate alerts to customers.Responsibilities: Analyzing the existing data flow to the warehouses and taking the similar approach to migrate the data into MongoDB. Created Partitioning, Bucketing, and Map Side Join, Parallel execution for optimizing the hive queries decreased the time of execution from hours to minutes. Involved in gathering requirements from client and estimating time line for developing complex queries using Kafka & NIFI streaming techniques.. Worked with cloud provisioning team on a capacity planning and sizing of the nodes (Master and Slave) for an Hortonworks (HDP) Platform Worked with Amazon EMR to process data directly in S3 when we want to copy data from S3 to the Hadoop Distributed File System (HDFS) on your Amazon EMR cluster by setting up the Spark Core for analysis work. Exposure on Spark Architecture and how RDD’s work internally by involving and processing the data from Local files, HDFS and RDBMS sources by creating RDD and optimizing for performance. Involved in data pipeline using Pig, Sqoop to ingest cargo data and customer histories into HDFS for analysis. Worked on importing data from My SQL DB to HDFS and vice-versa using Sqoop to configure Hive
