Key Responsibilities

• Responsible for designing, building, and maintaining responsive, high-performance front-end applications using React.js, while integrating with Java/Spring Boot REST APIs. This role focuses on creating modular UI components, implementing state management, ensuring quality through testing, and collaborating with design and back-end teams to deliver reliable user experiences.
• Roles and Responsibilities
• Build modular, reusable, and testable UI components (e.g., forms, buttons, dashboards) using JSX.
• Translate wireframes and UI designs into fully functional, responsive, and interactive front-end code.
• Implement state management using Redux and/or Context API and manage application behavior using React Hooks (e.g., useState, useEffect).
• Integrate front-end components with back-end services using RESTful APIs, including Java/Spring Boot API services.
• Optimize application performance using techniques such as code-splitting, lazy loading, and efficient rendering patterns.
• Write and maintain unit and integration tests using tools such as Jest and React Testing Library; troubleshoot and fix defects to ensure quality.

Requirements

• Proficiency with HTML5, CSS3, and React.js.
• Experience building component-based UI using JSX and modern React patterns (Hooks).
• Working knowledge of state management approaches (Redux and/or Context API).
• Experience integrating UI with RESTful APIs, including back-end services built with Java and Spring Boot.
• Experience with version control (Bitbucket) and modern front-end tooling (Webpack or Vite) and package managers (npm or yarn).
• Experience writing and maintaining unit/integration tests using Jest and React Testing Library.
• Familiarity with client-side routing using React Router.
• Familiarity with schema-based validation libraries such as Yup and Zod.
• Preferred Attributes
  - Experience with TypeScript.
  - Experience with Next.js and server-side rendering (SSR).
  - Strong understanding of responsive design, accessibility, and cross-browser compatibility.
  - Performance tuning experience for React applications (render optimization, bundling strategies).
  - Strong collaboration skills to work effectively with UI/UX, back-end engineering, and QA stakeholders.
• Certifications
  - React or modern front-end framework certification (vendor or recognized training provider).
  - Java and/or Spring Boot certification (e.g., Oracle Java, VMware Spring).
  - Cloud or DevOps certification (optional; role-dependent).
