• Automate routine database administration tasks via scripting, infrastructure-as-code (IaC), and CI/CD pipelines.
• Evaluate, recommend, and integrate new database technologies including cloud-native services, NoSQL, data lakes, and streaming platforms.
• Ensure data consistency, integrity, and availability across distributed geographies and payment systems.
• Analyze business needs and translate them into efficient data models, schemas, and data flows.
• Provide expert guidance on capacity planning, growth forecasting, and future-proofing the data platform.
