Datastage Developer

Involved in the design and development of ETL processes to load data for analytical purposes.Was responsible for building new data marts (SEO data mart) as well as enhancing the current ones with new features.Automated processes using the Unix shell scripts.Since processing of huge files from Omniture was involved, performance tuning of the mappings, sessions and workflows played a huge role in bringing down the running time.Co-ordinated with Omniture to resolve source file related issues.Wrote test cases for integration testing.Performed data profiling of the sources using Talend open source tool before beginning the development work. That helped me identify the data patterns.Analyzed data related issues and proposed possible solutions and picked the best one after the consultations based on ROI.Worked on the Revenue data mart which involved a lot of mappings with complicated data calculations where the totals have to absolutely precise.During development work, focused on reusability and simplicity to get the best performance.Used advanced mapping techniques to make the most of the Informatica tool.Worked with the users directly for requirements as well as any data related issues.Documented all the processes for the ease of understanding for the new recruits as well as for the existing ones.Have provided production support and resolved critical issues.
