• Leverage AWS services (e.g., EC2, S3, Lambda, RDS, CloudFront) for application deployment, monitoring, and scalability.
• Ensure application performance, security, and reliability across the stack.
• Participate in architecture reviews, provide mentorship to mid-level engineers, and drive best practices across the team.

• Solid understanding of microservices architecture and distributed systems.
• Experience with relational databases (e.g., PostgreSQL, MySQL) and ORM frameworks (e.g., Hibernate).

• Ability to translate complex business needs into technical solutions.
• Excellent problem-solving, debugging, and communication skills.

Preferred Qualifications:

• Experience with frontend performance optimization and state management (Redux, or similar).
• Familiarity with non-relational databases (MongoDB, DynamoDB).
• Knowledge of messaging systems (Kafka, RabbitMQ).
• Experience with monitoring and observability tools (CloudWatch, Prometheus, Grafana).
