As an ETL Developer, I specialize in designing and developing ETL processes using Informatica to integrate new data sources. I have successfully developed customized ETL mappings and workflows, increasing data load frequency by 100% to meet critical reporting deadlines. My expertise includes designing, developing, and maintaining ETL jobs using Tivoli Workload Scheduler, as well as debugging and troubleshooting errors in ETL jobs.I am skilled in enhancing existing processes to improve efficiency and performance, developing data models to support data integration, and testing and validating ETL processes. I also perform monitoring and maintenance of ETL jobs and collaborate with cross-functional teams to define data integration requirements and design solutions. Additionally, I develop data cleansing and data quality processes, prepare comprehensive documentation for production deployment, and utilize ServiceNow to raise change requests for implementing changes in the production environment.
