Node Js / React Js Developer

The Node.js / React.js Developer is responsible for building and maintaining robust web applications using Node.js for the back-end and React.js for the front-end. This role requires proficiency in JavaScript and its associated frameworks to create fast, scalable, and highly responsive applications. The developer will work closely with cross-functional teams to ensure that both the front-end and back-end components are seamlessly integrated to deliver a high-quality user experience.

Key Responsibilities :

• Back-End Development with Node.js : Build efficient, reusable, and scalable back-end services using Node.js and related frameworks (e.g., Express.js). Implement business logic, integrate APIs, and ensure seamless data processing.
• Front-End Development with React.js : Develop dynamic and responsive user interfaces using React.js, ensuring a smooth and intuitive user experience. Utilize React's component-based architecture to create modular and maintainable code.
• API Development and Integration : Develop RESTful APIs to support both the front-end and back-end of the application. Ensure that the APIs are efficient, well-documented, and easy to integrate with other services or third-party systems.
• Database Integration : Work with both SQL and NoSQL databases (e.g., MongoDB, MySQL, PostgreSQL) to design and implement data models. Write efficient queries to retrieve and store data, ensuring fast and reliable performance.
• State Management : Utilize state management tools (e.g., Redux, Context API) to manage complex state in large-scale React applications, ensuring smooth data flow between components.
• Testing and Debugging : Write unit and integration tests for both front-end and back-end components using testing frameworks like Jest, Mocha, or Jasmine. Debug and resolve issues in the development and production environments.
• Optimization and Performance Tuning : Optimize application performance on both the client and server side, ensuring fast load times and responsiveness. Use tools like Webpack, Babel, and Lighthouse to identify and resolve performance bottlenecks.
• Code Quality and Version Control : Ensure code quality by adhering to coding standards, writing clear documentation, and conducting code reviews. Use version control tools like Git to manage and collaborate on codebase.
• Collaboration : Work closely with designers, product managers, and other developers to deliver high-quality software that meets user requirements. Participate in sprint planning, stand-ups, and other Agile ceremonies.
• Security Best Practices : Implement security measures such as data validation, authentication (e.g., JWT, OAuth), and encryption to protect user data and prevent vulnerabilities.
• Continuous Improvement : Stay up-to-date with the latest industry trends, technologies, and best practices for both Node.js and React.js. Continuously enhance your skills and contribute to the improvement of development processes and tools.
• Deployment and Maintenance : Assist with the deployment of applications to production environments. Monitor the application post-deployment, addressing any performance issues or bugs that arise.

Skills and Qualifications :

• Educational Background : Bachelor’s degree in Computer Science, Software Engineering, Information Technology, or a related field.
• Proficiency in JavaScript : Strong understanding and hands-on experience with JavaScript, including ES6+ features, asynchronous programming (Promises, async/await), and functional programming concepts.
• Node.js Expertise : In-depth experience with Node.js, including knowledge of Express.js or similar frameworks for building RESTful APIs and web services.
• React.js Expertise : Strong experience with React.js, including hooks, functional components, JSX, and state management libraries like Redux or Context API.
• Database Knowledge : Experience with both relational and non-relational databases such as MongoDB, MySQL, or PostgreSQL. Familiarity with ORMs (e.g., Sequelize, Mongoose) is a plus.
• Front-End Technologies : Proficiency in HTML, CSS, and JavaScript. Familiarity with front-end build tools like Webpack, Babel, and NPM.
• Version Control : Expertise with Git and GitHub or other version control systems to manage codebase and collaborate with other developers.
• Testing : Experience with front-end and back-end testing frameworks such as Jest, Mocha, Chai, or Enzyme for unit and integration testing.
• API Integration : Strong experience with consuming and integrating third-party APIs, as well as building and exposing your own RESTful APIs.
• Agile Methodology : Familiarity with Agile development practices, including Scrum and Kanban, and the ability to contribute effectively to Agile ceremonies (e.g., sprint planning, retrospectives).
• Problem-Solving Skills : Strong analytical and troubleshooting skills, with the ability to quickly diagnose and resolve issues in both front-end and back-end code.
• Communication Skills : Excellent communication skills to interact with cross-functional teams, explain technical concepts clearly, and document processes.

Desirable Skills :

• Cloud Platforms : Familiarity with cloud platforms such as AWS, Azure, or Google Cloud for hosting applications and databases.
• Containerization and Orchestration : Experience with Docker and Kubernetes for containerizing and managing applications in a cloud environment.
• CI/CD : Knowledge of continuous integration and continuous deployment (CI/CD) practices and tools like Jenkins, GitLab CI, or CircleCI.
• Mobile Development : Familiarity with React Native for building mobile applications would be an advantage.
• GraphQL : Experience with GraphQL for building flexible and efficient APIs.
• DevOps Practices : Understanding of DevOps practices and experience with tools like Docker, Kubernetes, or Terraform for infrastructure management.
