I’m a results-driven ETL Developer with 7+ years of experience designing and optimizing data pipelines using Informatica PowerCenter, Informatica Cloud (IICS), SQL, and Python. I specialize in cloud data migration, pipeline performance tuning, and automation. I've led major migration initiatives: DataStage to IICS PowerCenter to IICS SQL Server to Snowflake By leveraging parameterization, dynamic mappings, and Python-based automation, I’ve consistently reduced job runtimes by up to 40% and improved delivery speed by 30%. My experience spans across: Cloud Platforms: Snowflake, Azure (ADF, Synapse, Power BI) ETL Tools: Informatica PowerCenter, IICS, DataStage, SSIS Databases: MySQL, Oracle, SQL Server Scripting & Automation: Python, Shell scripting Schedulers: Control-M, Automic BI & Reporting: OBI, QlikView, Power BI (learning) Agile & DevOps: Sprint-based delivery, version control, production deployment I collaborate closely with business stakeholders, source system teams, and QA to ensure data integrity, reusability, and maintainability.
