• Experience with NoSQL databases (DynamoDB, MongoDB, Cassandra, etc.)
• Experience with CI/CD pipelines and build/deploy automation
• Experience with event-driven systems and asynchronous messaging (e.g., Kafka)
• Experience with observability tools (logging, metrics, tracing) and production troubleshooting
Preferred Qualifications
