Key Responsibilities
Backend Development
Develop and enhance scalable backend services using Java 8+ and Spring Boot.
Build secure, high-quality RESTful APIs with proper validation, exception handling, and authentication / authorization.
Microservices Architecture
Implement microservices with best practices for service registry, configuration management, resiliency patterns (retry, circuit breaker), and asynchronous communication.
Ensure services are modular, fault-tolerant, observable, and optimized for performance.

Write optimized SQL queries, manage transactions, indexing, and database performance tuning.
Code Quality & Reviews
Write clean, testable, maintainable code using OOP, SOLID principles, and design patterns.
Conduct peer code reviews and participate in architecture and design discussions.
Cloud & DevOps Collaboration
Deploy and maintain applications on AWS (S3, EC2, RDS, IAM, CloudWatch, etc.).
Collaborate with DevOps teams on CI / CD pipelines, containerization (Docker), and automated deployments.
Testing & Quality Assurance
Write strong unit tests using JUnit, Mockito and ensure high code coverage.
Support integration testing, debugging, and issue resolution across environments.
Service Virtualization & Integrations
Use tools like WireMock, MockServer, or similar for service virtualization to simulate dependent systems.

Core Java (8+)
Strong understanding of OOPs, Collections, Streams, and Lambda expressions.
Familiarity with features from Java 11, 17, and 21 (switch expressions, var, records, virtual threads, pattern matching, etc.).
Spring Boot
Strong experience with Spring Boot modules, annotations, configuration, and application lifecycle.
Hands-on with Spring Web, Spring Data JPA, Spring Validation, Spring Security, and monitoring tools.
REST API Development
Deep understanding of REST architecture, pagination, versioning, idempotency, and API documentation (Swagger / OpenAPI).
Microservices
Good understanding of distributed systems, async messaging, logging / tracing (ELK, Prometheus, Loki, Grafana), and microservice best practices.
Database
Strong SQL and experience with relational database design, optimization, indexing, and ORMs (Hibernate / JPA).
Hands-on Coding
Ability to independently design, develop, debug, test, and deploy features end-to-end.
Secondary Skills (Good to Have)
Cloud – AWS (Preferred)
Experience with EC2, S3, IAM, Lambda, CloudWatch, ECS / EKS.
DevOps
Familiarity with CI / CD pipelines : Jenkins, GitLab CI, GitHub Actions.
Experience with Docker and containerization.
Kafka
Understanding of event-driven architecture, producers / consumers, topics, partitions, and offset management.
Unit Testing
Strong skills in JUnit, Mockito; exposure to TDD / BDD is a plus.
Service Virtualization
Experience with WireMock, MockServer, or similar tools.
Soft Skills
Strong analytical and problem-solving mindset.
Ability to work in Agile teams and collaborate cross-functionally.
Excellent communication and documentation skills.
