• Support near-real-time and lower-latency data processing where required
• Build data quality checks, automated assertions, lineage documentation, and dataset certification routines
• Apply least-privilege access patterns, dataset classification, auditability controls, and data minimization practices
• Collaborate closely with BI/Data Analysts to ensure schemas support dashboard and reporting needs

• Write runbooks and handover documentation to keep the platform maintainable long-term
