Full-Stack Developer (React & Node.js)

As a Full-Stack Developer at our company, you’ll be responsible for building dynamic web applications covering both front-end and back-end development. This includes creating responsive user interfaces with React and Material-UI, developing RESTful APIs with Node.js and Express.js, managing databases like PostgreSQL and MongoDB, and ensuring performance and security in applications.

Essential skills for a Full-Stack Developer role at our company include expertise in JavaScript, a deep understanding of React for front-end development, and experience with Node.js and Express.js for back-end processes. Proficiency in database management, API design, and familiarity with tools like Material-UI, Git, Docker, and testing frameworks like Jest and Cypress are also critical.

We look for candidates with a Bachelor's degree in Computer Science, Engineering, or related fields (or equivalent practical experience) with at least 6 years of professional experience in full-stack development. Strong expertise in JavaScript, React, Node.js, and familiarity with databases like SQL and NoSQL will set you on the right path to join our team.

In our company, the Full-Stack Developer role integrates DevOps practices by implementing CI/CD pipelines for automated builds and deployments. You'll also work on containerized applications using Docker, ensuring a smooth operational workflow that enhances collaboration across teams.

Collaboration is at the core of our development process. As a Full-Stack Developer, you will partner with cross-functional teams, participate in code reviews, and share constructive feedback to ensure robust solutions while contributing to a team-oriented environment.

In React, the component lifecycle consists of several stages: Mounting, Updating, and Unmounting. Mounting involves the creation of the component, while Updating happens whenever there’s a change in state or props. Unmounting occurs when a component is removed from the DOM. Understanding these stages helps optimize performance and manage state efficiently.

In a React application, state management can be handled using React's built-in state, Context API for simpler state across components, or using libraries like Redux or MobX for more complex state management needs. Knowing when to use each method is key to maintaining a responsive UI.

RESTful APIs are architectural styles for designing networked applications. They use stateless communication and standard HTTP methods like GET, POST, PUT, and DELETE to enable server-client interactions. Understanding REST principles allows you to create efficient endpoints that leverage HTTP methods effectively.

Jest is a powerful testing framework for JavaScript applications, allowing for unit and integration testing, while Cypress specializes in end-to-end testing. Both frameworks enable thorough testing of applications, ensuring reliability and performance through automated processes.

Responsive design is crucial in web development because it ensures that applications are accessible and visually appealing on all devices, from desktops to mobile phones. Using CSS frameworks like TailwindCSS can simplify the implementation of responsive design by providing utilities to create layouts that adapt to various screen sizes.

To optimize React application performance, consider techniques like code splitting, using React's memoization capabilities (React.memo, useMemo, useCallback), and optimizing component renders. Additionally, implementing lazy loading for components and images can drastically improve load times.

My experience with database management spans both SQL databases like PostgreSQL, where I write complex queries for data retrieval, and NoSQL databases like MongoDB, which allows for flexible schema designs. I have built efficient data models and optimized query performance as part of back-end development.

Version control, particularly using Git, plays a vital role in my development process by enabling collaborative coding, tracking changes, and managing branches. It ensures that all team members are on the same page, reduces conflicts, and allows for easier rollback to previous code versions when necessary.

In a recent project, I used Docker for containerization, allowing our applications to run in consistent environments across different platforms. This minimized the 'works on my machine' problem and enabled easier deployments and scalability with various microservices.

Effective API design strategies include keeping endpoints intuitive, versioning APIs, ensuring robust documentation, and adhering to REST guidelines. It’s also essential to manage authentication and rate limiting to create a secure and user-friendly API experience.
