\n

 * Strong hands-on AWS and PostgreSQL expertise, including infrastructure as code, ECS Fargate, Aurora PostgreSQL, S3, schema design, and performance optimization.
\n

 * Experience using agentic coding tools effectively and building systems with agentic workflows.
\n

 * The judgment to rigorously review AI-generated code while maintaining ownership of engineering quality and daily execution.
