How to write yours — Database Administrator tips
- Replace generic duties with concrete metrics: cite specific performance improvements (e.g., '40% RTO reduction') rather than listing responsibilities.
- Demonstrate AI/ML awareness by mentioning experience with analytics workloads, data pipeline optimization, or supporting ML model training infrastructure.
- Highlight cloud proficiency (AWS RDS, Azure SQL, Google Cloud) and modern tools (Kubernetes, containerization) rather than on-premises-only experience.
- Include one sentence about your employer research to show genuine interest in their data strategy, not a template application.
- Use technical vocabulary accurately (RPO, RTO, sharding, materialized views) to establish credibility without buzzwords like 'synergy'.
