• Perform detailed source-to-target mapping, data transformation analysis, reconciliation, and validation as part of large-scale data migration initiatives. 

• Collaborate with data modelers and architects to align conceptual, logical, and physical data models with migration and integration requirements. 

• Produce and maintain migration design documents, Low-Level Design (LLD), mapping specifications, unit test plans, and validation reports. 

• Provide technical guidance to testing, integration, and downstream teams on migration logic, data validation strategies, and testing expectations. 

• Support integration testing and UAT by validating data consistency and correctness across upstream and downstream systems. 

• Perform in-depth troubleshooting, root cause analysis, and resolution of migration-related data issues across environments. 

• Ensure adherence to data governance standards, security controls, performance guidelines, and cloud best practices. 

• Proactively manage work items, timelines, dependencies, and risks; communicate issues and trade-offs to technical and business stakeholders. 

• Participate in SCRUM ceremonies; work closely with onsite and offshore teams while maintaining ownership of assigned deliverables. 

• Assist with documentation and artifacts for security clearance, release readiness, and production deployment.
