• Keep it clean and compliant: Implement rigorous data validation, logging, and audit trails aligned with industry standards.
• Troubleshoot at scale: Diagnose and resolve performance bottlenecks in high-speed, event-driven environments where milliseconds matter.
• Architect the flow: Design and document table structures, relationships, and data pipelines supporting financial operations and APIs.
• Collaborate cross-functionally: Partner with product, engineering, and risk teams to translate complex business logic into rock-solid database solutions.

• Continuously optimize: Tune queries, refine processes, and find smarter ways to move, store, and retrieve data efficiently.
