React & Node.js Full-Stack Developer for Existing Project Module

Expert React and Node.js Full-Stack Developer Needed for Existing Project Project Overview We are looking for an experienced full-stack developer to implement a new module and additional features in an existing web application. The project is already set up and under active development. The selected developer will not need to build the application from scratch. You will be expected to understand the existing architecture, follow the current coding patterns, and implement the assigned module without affecting other functionality. The frontend is developed in React, and the backend consists of Node.js APIs. This initial assignment will focus on one module. However, there is a strong opportunity for ongoing and larger development work if the task is completed on time and according to our coding and quality standards. Initial Scope of Work The selected developer will be responsible for: Reviewing the existing React and Node.js project structure Understanding the current coding standards and application flow Implementing the assigned custom module Developing the required React screens and components Creating or updating Node.js API endpoints Integrating frontend functionality with backend APIs Implementing database operations where required Adding form validations and proper error handling Managing loading, empty and error states Following the existing UI design and responsive layout Testing the complete module before delivery Fixing issues identified during our review Ensuring that existing functionality is not affected The complete module requirements, designs and workflow details will be shared with the shortlisted developer. Technical Requirements The developer should have strong practical experience with: React.js JavaScript or TypeScript Node.js REST API development and integration Database operations Authentication and authorisation Role-based access and permissions Form validation Responsive frontend development Git and GitHub Debugging existing applications Clean and reusable code API error handling Existing codebase maintenance Experience with state-management libraries and modern React development practices will be an advantage. Coding Standards We are looking for someone who writes production-quality code. The developer must: Follow the existing project architecture Keep frontend and backend code properly organised Create reusable React components where appropriate Avoid unnecessary duplication Use clear and consistent naming conventions Write readable and maintainable code Add comments only where they provide meaningful clarification Validate data on both the frontend and backend Handle API errors properly Avoid hard-coded values Protect secure API endpoints Follow the existing database and migration structure Test all implemented functionality Avoid breaking any existing modules Submit clean Git commits with meaningful messages Please do not introduce new libraries, frameworks or architectural changes without discussing them with us first. Expected Deliverables The final delivery should include: Completed React frontend functionality Completed Node.js API functionality Required database changes or migrations Frontend and backend validations API integration Responsive implementation Tested and working module Clean source code committed through Git Brief documentation explaining the implemented functionality Support for resolving issues found during final review The task will only be considered complete after the module has been tested successfully and all agreed requirements are working. Working Process Our expected working process is: Review the existing project and module requirements Confirm your understanding of the workflow Provide a clear implementation approach Develop the module according to the existing standards Share regular progress updates Submit code through the agreed Git workflow Complete testing and resolve review feedback Deliver the final working module Good communication and transparent progress updates are important for this role. Long-Term Opportunity This is the first assignment in an existing and growing project. If the selected developer: Delivers the module within the agreed timeline Follows our coding standards Communicates clearly Writes maintainable code Completes proper testing Does not affect existing functionality there will be a significant opportunity for ongoing work, including additional modules, new features, improvements and long-term project support. We are interested in building a reliable long-term working relationship with the right developer.
