• Perform end-to-end data validation from source systems through ETL processes to downstream reporting applications
• Analyze and validate data across multiple database systems, including Oracle SQL Developer, MySQL, and Microsoft SQL Server
• Validate ETL/ELT pipelines, data transformations, and business rules within Microsoft Fabric using SQL and Py Spark
• Review and validate API integrations, including request/response structures, status codes, and protocols
• Analyze and validate JSON and XML data structures across systems and integrations
• Validate Power BI reports and dashboards by verifying calculations, filters, drill-through functionality, visualizations, KPIs, security, and user experience
• Design and execute validation strategies for large-scale data processing and integrations
• Collaborate with development teams and data engineers to ensure alignment with mortgage processes and KPIs
• Communicate testing progress, risks, and results clearly to stakeholders and leadership
• Support and guide QA processes, including risk identification and mitigation strategies
