• Integrate with internal systems, third-party services, messaging platforms (Kafka, RabbitMQ), and external APIs
• Write comprehensive unit and integration tests using JUnit 5, Mockito, or TestContainers; maintain high code coverage standards
• Actively use AI coding assistants (e.g., GitHub Copilot, Claude Code, Gemini etc. ) to boost productivity, generate boilerplate, and explore solutions
• Apply prompt engineering techniques to leverage LLMs for debugging, code review, documentation generation, and test case creation
• Work in an Agile/Scrum environment with iterative delivery cycles, sprint planning, and continuous improvement
