• Improve production SQL for performance, scalability and data accuracy.
• Automate workflows using orchestration platforms such as Airflow and Control-M.
• Design scalable data models to capture sequential, time-dependent, and event-driven customer journey data.
• Apply version control best practices using Git, including branching, code reviews, CI/CD integration, and deployment standards.
• Use AI and machine-assisted development responsibly to enhance productivity and quality without compromising maintainability.
• Collaborate to translate our needs into, automated data solutions that provide measurable impact.
• Evaluate and integrate AWS data services and tools to improve performance and cost-effectiveness.
