Key Skills
- Strong hands-on coding experience in backend development.
- At least 5+ years of experience developing APIs and microservices using Java (preferably Java 11+; Java 21 experience strongly preferred).
- Deep experience with Spring Boot for building RESTful services, including dependency injection, validation, configuration management and actuator.
- Strong understanding of REST API design, versioning, error handling and documentation (e.g., OpenAPI/Swagger).
- Experience with caching frameworks (e.g., Redis, Caffeine) and patterns to improve performance and scalability.
- Experience with SQL databases and ORM frameworks (JPA/Hibernate), plus exposure to NoSQL/persistence patterns as applicable.
- Good understanding of microservices architecture concepts such as service discovery, configuration management, resilience and API gateways.
- Familiarity with Git, CI/CD pipelines and containerization (Docker; Kubernetes exposure is a plus).
- Awareness of security best practices for APIs (authentication, authorization, OWASP considerations) in a financial services environment is preferred.
