- Participate actively in data validation processes to ensure data accuracy, completeness, and consistency

- Implement and enforce non-functional requirements including performance optimization, security controls, privacy standards, and GDPR compliance

- Recommend and implement improvements to enhance data reliability, quality, and operational efficiency

Collaboration & Innovation:

- Work closely with cross-functional teams and external vendors to align on technical requirements and delivery timelines

- Integrate emerging data management and software engineering technologies into existing data structures
