## About

Immediate Joiner AWS Data Engineer with nearly 3 years of experience building scalable data pipelines and distributed data processing systems on AWS\. Experienced in designing and optimizing large\-scale ETL pipelines processing 2–3 TB of daily data across Amazon S3, Snowflake, and REST APIs using PySpark and Apache Spark on AWS EMR clusters\. Strong experience in building Data Lake architectures using Medallion \(Bronze → Silver → Gold\) architecture, enabling reliable data ingestion, transformation, and analytics for downstream consumers using Amazon Athena\. Key expertise includes: • Distributed data processing using PySpark and Apache Spark • Building scalable ETL pipelines on AWS EMR clusters • Designing S3\-based Data Lake architectures • Data ingestion from APIs, Snowflake, and cloud storage • Spark performance optimization \(broadcast joins, partition pruning, executor tuning\) • Handling production challenges such as data skew, schema evolution, and pipeline failures • Workflow orchestration using AWS Step Functions In my recent role, I designed and maintained distributed PySpark pipelines on a 30\-node AWS EMR cluster processing up to 2–3 TB of daily telecom and analytics data\. I optimized Spark workloads which reduced pipeline runtime by more than 2 hours while maintaining SLA\-based batch processing reliability\. I am currently open to new opportunities and available to join immediately for Data Engineer roles focused on AWS, Spark, and large\-scale data platforms\.
