• create automated unit, component, and consumer-driven contract tests to build quality and testability into every change
• work with event-driven architecture, REST APIs, messaging, databases, and distributed application patterns
• pair with colleagues on more complex tasks, participate in code reviews, and learn through practical feedback
• contribute to technical and design discussions, ask questions, and share your ideas and perspective
• apply AI-assisted software engineering in practice to support development, testing, problem-solving, and learning
• collaborate within an agile team and gradually build your understanding of modern software engineering principles and practices
