As an Azure Data Engineer at Tata Consultancy Services, I specialize in building scalable data solutions on Azure Databricks. My work includes engineering reusable L1 ingestion pipelines with PySpark and SQL, optimizing ETL workflows, and implementing advanced data modeling techniques such as Star/Snowflake schemas, Delta Lake optimization, and partitioning. I focus on performance tuning and large‑scale data processing, consistently delivering measurable improvements in query speed, latency reduction, and pipeline efficiency. I have architected complex reporting pipelines and SQL‑driven models that support consumer goods analytics, including demand forecasting, BOM analysis, and NLP‑based supplier insights. My expertise spans SQL query development, PySpark transformations, and data validation, ensuring accuracy and reliability across datasets exceeding 100M+ records. By combining strong technical depth with cloud‑native engineering practices, I enable robust, reusable data assets that power enterprise‑grade analytics and BI solutions.
