- Problem Solving: Troubleshoot and resolve technical issues, defects, and blockers related to data migration scripts, database connectivity, and data quality.
- Collaboration: Work closely with Business Analysts to understand data requirements and with QA testers to validate migration results, ensuring deliverables align with project objectives.
- Documentation: Create and maintain clear technical documentation for migration processes, code, and configurations to support ongoing development and maintenance.
- Sensitive Data Handling: Adhere to the highest standards of security and confidentiality when handling sensitive Personally Identifiable Information (PII) and Special Personal Information (SPI).
