• Implement reusable UI components and patterns to support consistent design across the application
• Integrate frontend applications with backend services via REST APIs (and GraphQL where applicable)
• Optimize performance (bundle size, rendering efficiency, caching, lazy loading) and ensure cross-browser compatibility

Backend (Java/Spring Boot):

• Develop and maintain backend services using Java and Spring Boot (RESTful services, validation, security)
• Design scalable APIs and service-layer architecture (controller/service/repository patterns)
• Build and manage data persistence using SQL and/or NoSQL databases, including schema design and query tuning
• Implement authentication/authorization (JWT/OAuth2, SSO, role-based access control)

Quality, Delivery, and Collaboration:

• Write unit and integration tests for frontend and backend; participate in code reviews and contribute to engineering standards
• Collaborate in Agile ceremonies (standups, sprint planning, refinement, retrospectives)
• Troubleshoot production issues, perform root-cause analysis, and implement sustainable fixes
• Contribute to CI/CD pipelines and environments (build, test, deploy automation)
• Document technical designs, API contracts, and support runbooks where needed

• 3+ years of professional software development experience (or equivalent practical experience)
• Strong backend development experience in Java and Spring Boot: REST APIs, dependency injection, Spring MVC, JPA/Hibernate (or similar ORM)
• Familiarity with microservices patterns (where applicable)
• Strong frontend development experience with React: Modern JavaScript/TypeScript, component design, hooks; Experience with at least one state management approach (Redux, Context API, Zustand, etc.)
