What I'm looking for

I am looking for a role that offers opportunities for growth, collaboration, and innovative data solutions.

I am a seasoned ETL developer with over 7.5 years of experience in the data integration domain, specializing in Informatica PowerCenter and Informatica Cloud. My expertise lies in developing complex mappings, workflows, and reusable components, as well as performing ETL and SQL performance tuning for large data volumes. I have a strong command of SQL and analytical functions, and I am adept at handling both structured and non-relational data sources.

Throughout my career, I have successfully collaborated with onshore and offshore teams to ensure timely and high-quality delivery of data solutions. I have been actively involved in Agile/Scrum ceremonies, contributing to the development of enterprise data warehouses and data marts for various clients, including HCSC and Truist Financial. My experience includes integrating cloud applications with on-prem systems, implementing data quality checks, and managing end-to-end workflows in development and testing environments.

My technical skills extend to working with CI/CD pipelines, utilizing Git for version control, and developing REST API integrations. I am committed to continuous improvement and have a proven track record of optimizing ETL processes to enhance performance and efficiency.
