Sandhiya Jayavel

I’m a Detail-oriented Data Analyst with 5 years of experience in data analysis, requirement gathering, and metadata documentation. I specialize in working with large-scale financial data and enterprise data warehouses, and I’ve built strong banking-domain expertise through work with one of the top U.S. banking clients.

I collaborate with business stakeholders to translate data requirements into technical specifications and transformation logic. I analyze data warehouse tables, design business logic for transformation and reporting layers, and create detailed source-to-target data mapping documents to support ETL implementation using Informatica PowerCenter and BDM. I also run comprehensive data profiling in Informatica Analyst to identify data quality issues and recommend fixes.

I support teams with accurate, well-structured metadata, logic derivation, and cross-functional communication. I’ve led root cause analysis on data mismatches and integrity issues to improve data trust and usability, and I designed Python automation tools that significantly reduced manual effort. I’ve also acted as a liaison between business users, development, and offshore teams, and led and coordinated a team of data analysts from offshore.
