Worked as an ETL developer for the client 'Selective Insurance Company of America' from March 2021 to the present. The project focuses on enhancing and building predictive models to detect fraudulent claims by developing an analytical engine using Informatica PowerCenter, IICS, and analytics platforms like Statistica and Microsoft Azure ML.

  • I optimized legacy code through various techniques to address and resolve performance issues.
  • Created IICS mappings and tasks, and migrated modeling/live score datasets from On-Prem SQL Server databases to cloud in parquet file format for Azure ML to support predictive model development.
  • I developed SCD Type-1 and SCD Type-2 mappings using both Informatica PowerCenter and IICS.
  • Utilized the Undraleu tool to ensure coding standards for developed mappings and implemented necessary changes based on Undraleu reports.
  • Collaborated with the scheduling team to automate Informatica/IICS mappings using ASG Zena workstation, aligning job schedules with business requirements

  • Executed DDL and DML commands to create, modify, and update data in SQL Server 2014 and 2019 tables.
  • Utilized Git integrated with DevOps for version control of AzureML pipelines.
  • Actively participated in agile ceremonies, managing sprint planning, grooming, retrospectives, and communicated with the product owner to gather requirements.
  • Served as a project DBA, performing tasks such as creating user logins, managing user access (native users, service accounts), and setting up linked servers on SQL Server 2014 and SSMS 2019.

  • Addressed and resolved production and non-production issues promptly to meet SLA requirements.
  • Possess fundamental skills in Cognos for running reports and testing, as well as in PowerBI for connecting to workspaces/datasets/dashboards and creating sample reports.
  • I enhanced the Cognos reports according to business requirements, developed and migrated them to CI, conducted regression testing, and then promoted them to production.
  • Skilled in navigating Azure Data Lake (ADL) and executing pipelines in Azure Machine Learning (AML).
  • Regularly met project deadlines by efficiently managing time and prioritizing tasks based on the importance.
  • Created effective communication channels within the team, enhancing collaboration among members throughout project development phases.
  • Performed detailed code reviews to uphold high code quality standards by adhering to best practices.
