• Collaborate closely with Data Engineers and business stakeholders to define and validate curated datasets optimized for analytics and AI use cases. • Specify and document data requirements, feature definitions, and aggregation logic for downstream analytical and machine learning applications. • Validate data completeness, consistency, and statistical soundness of serving-layer datasets. • Provide continuous feedback to data engineering teams on data model usability, performance, and analytical fitness. • Perform exploratory data analysis (EDA) to identify patterns, anomalies, and data quality issues. • Build and test baseline machine learning models and analytical prototypes using curated datasets. • Contribute to the design and implementation of lightweight ML pipelines (training, evaluation, inference) aligned with platform standards. • Ensure features and models are reproducible, versioned, and prepared for future operationalization in production environments.
