• Produce thorough model documentation, including entity-relationship diagrams, data dictionaries, and metadata records, enabling easy reference, maintenance, and auditing of data models

Continuous Improvement & Adaptability:

• Profile source data and analyse data quality issues, making adjustments to models to meet established standards for accuracy, consistency, and compliance.
• Take part in proofs of concept (POCs), pilot projects, and sandbox environments to test model designs, ensuring they remain robust, future-ready, and responsive to regulatory changes and emerging technologies in the data and analytics landscape.
