Sai Gireeshmaa Mula

I’m a Senior Software Engineer focused on Data Engineering, with 5+ years designing and optimizing ETL/ELT solutions across Azure. I build reliable data platforms using Azure Data Factory, Microsoft Fabric, Azure Synapse, Databricks, and PySpark, with a strong emphasis on performance and maintainability.

At Yash Technologies, I designed metadata-driven ADF/Synapse/Fabric pipelines for SAP, REST API, and SFTP ingestion into ADLS. I parameterized reusable pipelines, reducing duplicated development by 40%, and improved ETL performance by 30% by developing PySpark and Spark SQL notebooks in Databricks/Fabric.

I’m also hands-on with governance and delivery excellence: I automated Azure Purview scans using Logic Apps to eliminate manual governance activities, and I implemented CI/CD using Azure DevOps across Development, UAT, and Production environments. I optimize SQL queries and stored procedures to improve report execution by 35%, and I model data with Star Schema and SCD Type2 for historical tracking.

Previously at Tata Consultancy Services (TCS), I built ETL/ELT pipelines using ADF, Databricks, SQL, and Azure Synapse, integrated SAP and enterprise data into Azure Data Lake, and reduced execution time by 35% through SQL optimization and indexing strategies. I resolved production incidents and data discrepancies while maintaining 99.9% pipeline reliability, and I translate requirements into scalable solutions by partnering with Product Owners, QA, Business Analysts, and stakeholders.
