Hi,I’m an Informatica ETL Developer with 5+ years of experience in data integration, data migration, and data warehousing, delivering scalable and high-performance data pipelines across enterprise systems.I specialize in designing, developing, and maintaining Informatica ETL solutions using Informatica PowerCenter / IICS, with strong expertise in source-to-target mapping, data transformation, and workflow orchestration. My hands-on experience includes working with complex transformations such as Lookup, Joiner, Aggregator, Expression, Router, Filter, and Update Strategy, along with implementing error handling, logging, and recovery mechanisms.I have extensive experience migrating and integrating data between relational databases (SQL Server, Oracle) and Salesforce / FinancialForce, ensuring data accuracy through profiling, cleansing, reconciliation, and validation. I actively perform ETL performance tuning using partitioning, pushdown optimization, indexing strategies, and workflow optimization.In addition, I use SQL and Python to support external data ingestion, automation, and data validation, and collaborate closely with analytics and business teams to deliver trusted, analytics-ready datasets. Currently, I am focused on building advanced data pipelines and applying machine learning models on integrated enterprise data to enable data-driven decision-making.I’m passionate about solving complex data challenges and building robust, scalable ETL architectures that transform raw data into meaningful insights.
