Background

About Hemachandra Katari

I'm a Data Engineer passionate about building scalable, reliable, and modern data systems that empower decision-making. Over the past four years, I've developed, optimized, and migrated complex data workflows in fast-paced environments—from banking and retail to healthcare. My expertise lies in engineering end-to-end data pipelines using Python, SQL, and Apache Spark, and orchestrating them with tools like Airflow and Azure Data Factory. I’ve successfully led cloud transformation projects on AWS, Azure, and GCP, helping organizations move from legacy systems to efficient, cloud-native architectures. One of my proudest achievements was improving a bank's ETL processing time by 40% through query optimization and strategic partitioning in Redshift. I've also helped a Fortune 100 retailer centralize data across 50+ global stores, enabling faster, cleaner reporting. I believe in combining technical depth with cross-functional collaboration. Whether it’s ensuring HIPAA or CCAR compliance, aligning data models with BI teams, or supporting machine learning workflows, I bring a solutions-focused approach to every challenge. I'm always open to connecting with professionals who are navigating the evolving data landscape or building next-gen platforms. Let’s talk data.
