Supriya Tavanshi

I am a Data Engineer with over 3.5 years of hands-on experience designing and implementing ETL workflows, data migrations, and cloud integrations using Informatica IICS/IDMC and CDI. I have worked extensively with Oracle, SQL Server, Salesforce and flat-file sources to build scalable, production-ready data pipelines.

I have led 15+ data migration and integration projects across EMEA and APAC, achieving significant performance improvements including an 83% reduction in ETL execution time and a 50% decrease in data errors. I build reusable Informatica mapplets and modular ETL components, and I implement SCD Types 1, 2 and 3 to maintain accurate historical data.

My technical toolkit includes Java embedded in mappings, Python automation for XML/JSON conversions and Azure Service Bus integrations, and practical exposure to Azure, Hadoop, Databricks, and Spark. I emphasize data quality practices—profiling, cleansing, rule specification and verification—throughout the pipeline lifecycle.

I have taken technical and functional leadership roles, mentoring junior developers and maintaining delivery continuity in the absence of the team lead. I hold Azure Developer Associate and several Infosys certifications, and I am focused on delivering high-quality, scalable data solutions.
