• Configure and manage data sources, connection pools, and subject areas to ensure high-performance reporting and secure access.
• Set up and manage Schedulers, Agents, and Jobs in OAC to enable automated delivery of reports and alerts to business users.

• Build and maintain datasets within DV and across subject areas to ensure reuse, consistency, and optimized performance.
• Drive the migration of legacy Oracle Discoverer reports to OAC, including analysis, mapping, validation, and performance tuning.
• Work closely with Oracle EBS functional leads to extract meaningful business insights across modules like Financials, Procurement, HR, and SCM.

Power BI Architecture & Development

• Translate functional and business needs into technical designs and reporting solutions in Power BI, ensuring accuracy, performance, and usability.
• Build enterprise-grade Power BI data models (star/snowflake schemas), custom DAX calculations, and dataflows using Power Query.
• Design visually engaging and user-centric reports following best UI/UX practices, ensuring clarity and actionable insight for stakeholders.
• Ensure seamless integration with on premise or cloud data sources, and enforce row-level security, data refresh schedules, and version control.

End-to-End BI Project Delivery

• Drive complete BI project lifecycle: requirements gathering, data discovery, architecture, development, UAT, deployment, and hyper-care.
• Collaborate with business users, Oracle functional teams, DBAs, and other BI developers to ensure alignment on data definitions, timelines, and deliverables.
• Proactively monitor performance, usage, and adoption of OAC and Power BI reports and recommend enhancements.
• Maintain documentation of technical architecture, RPD logic, data flows, and report inventory.
