Java Back End Developer

Design, develop, and maintain RESTful microservices using Java (8/11/17/21) and Spring Boot (3.x). • Implement microservice patterns with Spring Cloud (service discovery, config management, API gateway, resilience). • Write clean, maintainable, and testable code following best practices. • Develop and consume REST APIs, ensuring proper documentation with OpenAPI/Swagger. • Integrate with relational (PostgreSQL, MySQL) or NoSQL (MongoDB, Redis) databases using Spring Data JPA. • Collaborate with DevOps teams for CI/CD pipelines using Jenkins, GitHub Actions, or similar tools. • Build and containerize services using Docker; work with Kubernetes for deployment (nice-to-have). • Implement unit, integration, and contract tests using JUnit, Mockito, and Pact. • Monitor applications using Spring Boot Actuator, Prometheus, Grafana, or ELK stack. • Work with messaging systems (Kafka, RabbitMQ, ActiveMQ) for event-driven architectures. • Ensure secure application development using OAuth2, JWT, or Keycloak.
