  • Worked with data architects and participated in the data modeling, database design and data warehouse design.
  • Involved in data migration for loading data from source database into destination database.
  • For one of the projects (AMS), designed the end-to-end architecture including developing the data model, designed the database and data warehouse, ETL process, SSRS report and SharePoint web dashboard page.
  • Create stored procedures, table valued functions, scalar functions data manipulation.
  • Designed the ETL database, data marts, Dimensional Model with Fact and Dimension tables.
  • Designed the ETL Refresh Data Model master package using SSIS which contains collection of several master packages running several child packages in different stages.
  • Converted the ETL process into a 1 package execution which scheduled to run refresh on AutoSYS
  • Created ETL packages to extract the data from disparate data sources, Microsoft Excel files with data in multiple sheets, .CSV files, Oracle RDR source, Safe net files, corner stone files, SharePoint list etc., apply transformation logic using Containers (For Each loop, Sequence and For Loop), control flow tasks and dataflow tasks and load the data into target tables.
  • Created the ETL packages in a way that avoid using the stored procedures and replace the code to in-line SQLs within the execute SQL task and convert the stored procedure code to SQL files and retrieve into SSIS using the “file connection” connection manager. This method is to eliminate the CRQ deployment process of databases changes from DEV to PROD.
  • Generated SSAS tabular cubes, created measures using DAX expressions, hierarchies, partitions, generated SSRS reports connecting to Tabular cubes using SSRS 2016 new query designer feature to connect cube and write MDX & DAX expressions in it.

  • Developed reports directly connecting to SSAS from SSRS and designed several reports.
  • Heavily worked on new SSRS reports, existing reports, report performance issues and report support issues for the different UI dashboards.
  • Tuned the SSRS reports using the concepts of parameter sniffing, aggregated calculations in stored procedures instead in the report Tablix, sorting in SP instead in Tablix, create a separate summary table with measures and parameter fields for summary report, do INSERT INTO Summary table from SELECT, create indexes on parameter columns and other SP tuning techniques to improve the performance for the large volumes of data.
  • Used SQL Profiler, Actual and estimated execution plans to troubleshoot the Stored Procedure Table Scan, Index Scan, Index Seek, Key Lookup, loop and Sort etc. issues.
  • Involved in the presentation and demo of the application to the internal Agency users, to get their suggestions and feedback.
