Cloud Database Management
- Administer cloud-managed database services on AWS (RDS, Aurora, DynamoDB), GCP (Cloud SQL, Spanner), or Azure Database platforms.
- Architect cloud-native database solutions with a focus on scalability, resilience, and cost optimisation.
- Lead zero-downtime migrations from on-premises databases to managed cloud services.
- Continuously evaluate emerging cloud database technologies and recommend adoption where appropriate.
Performance Tuning & Capacity Planning
- Analyse slow queries, index strategies, and execution plans; implement targeted optimisations to meet SLA requirements.
- Conduct regular capacity planning and performance benchmarking across all environments.
- Collaborate with application engineers to review ORM usage and data models for performance at scale.
