Back-End Engineer (Java Spring Boot): implement customer RESTful API

Example Company is a mid-sized software development firm specializing in customer management solutions. The company uses Java Spring Boot for backend development, Docker for containerization, and Jenkins for continuous integration and deployment. These tools enable streamlined software delivery, achieving deployment times of under 15 minutes and reducing build errors by 30%.

The company recently launched a scalable API for a major retail client, integrating legacy backend systems with modern frontend applications. This API reduced data retrieval times by 40% and achieved a 99.98% uptime over six months. Metrics like average response times of 180ms, a 25% increase in customer satisfaction scores, and a 15% boost in client retention rates highlight the company’s technical precision and ability to deliver impactful solutions.

Collaboration is key to Example Company’s success. Weekly cross-functional meetings ensure alignment between technical teams and business stakeholders, while rigorous code reviews focus on scalability, maintainability, and adherence to RESTful principles. Despite challenges in balancing usability and scalability, the company leverages open communication channels and retrospectives to address trade-offs effectively.

You will step into the role of a Java Backend Developer tasked with designing and implementing REST API endpoints for a customer management system. Your focus will be on the CustomerController.java file, where you will create methods for retrieving and creating customer records while adhering to RESTful principles.

In real-time chat, you will collaborate with Julia Morales, the Product Manager, who will provide feedback and challenge your technical decisions. You must justify your choices, balancing simplicity for immediate usability with extensibility for future scalability. Additionally, you’ll address concerns about predictable response formats, compatibility with legacy systems, and performance optimization.

Your mission is to refine the collaborative asset by implementing the required methods, applying Spring Boot annotations, and ensuring alignment with both technical standards and stakeholder priorities.

• Implement REST API endpoints in the CustomerController.java file, including methods for retrieving all customers and creating new customer records.
• Use appropriate Spring Boot annotations to ensure compliance with RESTful principles.
• Engage in real-time chat with Julia Morales to justify your technical decisions and address her concerns about response formats, scalability, and simplicity.
• Ensure the API design aligns with legacy system constraints and maintains optimal performance.
• Deliver a well-structured and functional collaborative asset that meets stakeholder expectations and technical requirements.
