Key Responsibilities

• Design, develop, and maintain scalable Java / Spring Boot applications for enterprise systems.
• Apply object-oriented and SOLID design principles to produce clean, maintainable, and reusable code.
• Implement multi-threaded and concurrent applications, ensuring performance, safety, and scalability.
• Develop and integrate RESTful APIs, event-driven, and message-driven microservices (Kafka, JMS, etc.).
• Collaborate with architects and DevOps teams to containerize and deploy applications (Docker, Kubernetes).
• Participate in code reviews, refactoring efforts, and design discussions to improve overall quality.
• Contribute to CI / CD pipelines, automated builds, and testing frameworks.

Required Skills & Qualifications

• 5–7 years of professional experience developing enterprise-grade applications.
• Deep understanding of Java (8 or above), Spring / Spring Boot, and microservice architecture.
• Strong grasp of OOP principles, SOLID design patterns, and common refactoring techniques (e.g., addressing 'God class' and tight coupling).
• Proven experience implementing multi-threaded, asynchronous, and concurrent applications.
• Hands-on experience with distributed technologies such as Kafka, RabbitMQ, or distributed caching (Redis, Hazelcast, etc.).
