Durga Kadium

I’m a SQL & SSIS Developer with around 4 years of experience designing and supporting ETL solutions using SQL Server and SSIS. I focus on building reliable data pipelines for reporting and business analytics, with strong T-SQL skills and an emphasis on incremental data loads.

At TATA Consultancy Services (TCS) from Jan 2022 to July 2025, I worked on an enterprise financial data integration and reporting platform for a Goldman Sachs client. I consolidated transaction, reference, and financial data into a centralized SQL Server reporting environment to support daily, end-of-day, month-end, and regulatory reporting.

I designed and developed SSIS packages (Control Flow and Data Flow) to extract data from databases, flat files, and Excel, and implemented transformations using Lookup, Derived Column, Conditional Split, Data Conversion, and Union All. I also developed and optimized T-SQL queries with complex joins, subqueries, CTEs, and window functions, maintained data integrity with constraints and indexes, and supported production through monitoring, root cause analysis, and performance tuning.
