    (retries, DLQs, monitoring, failure recovery).
    — Optimize PostgreSQL (Amazon RDS) performance and reliability
    (indexes, migrations, scaling strategies).

    — Collaborate closely with frontend and product teams.
    — Contribute to architecture and technical decision-making.

    What we’re looking for:

    — Skills with Serverless Framework and serverless.yml (stages, variables, IAM roles, plugins, CI/CD).
    — Production experience with Amazon RDS (PostgreSQL).
    — Confident use of Amazon SQS: standard vs FIFO queues, retries, DLQs, idempotency, visibility timeouts and backpressure patterns.
    — Strong understanding of REST API design.
    — Observability experience: CloudWatch logs & metrics, alarms, structured logging, basic tracing.
    — Deep understanding of security fundamentals: IAM least-privilege approach, secrets management (SSM / Secrets Manager), encryption basics, VPC fundamentals.
