Mern Stack Developer

Roles & Responsibilities

• Develop modern, scalable, and responsive web applications using ReactJS.
• Build cross-platform mobile applications using React Native for a single app across iOS and Android.
• Create reusable UI components and frontend libraries for faster development.
• Integrate frontend applications with backend services, REST APIs, and third-party integrations (limited to 12 core integrations, e.g., payment gateway, maps, or push notifications).
• Design and manage MongoDB database schemas for CRUD-focused, moderately complex data models.
• Develop and maintain Node.js-based backend modules for the application's API layer, authentication, and core business logic.
• Optimize applications for speed, scalability, and performance across browsers and mobile devices.
• Generate Android and iOS production builds, perform testing, and publish the application to the Google Play Store and Apple App Store.
• Collaborate closely with UI/UX designers, backend developers (if applicable), QA engineers, and project managers.
• Debug, troubleshoot, and resolve application issues efficiently.
• Follow coding standards, security best practices, documentation, and version control processes.
• Use AI-assisted development tools throughout the workflow to speed up scaffolding, debugging, refactoring, and documentation while maintaining ownership and understanding of all shipped code.

Core Technologies

• Strong hands-on experience in ReactJS and JavaScript (ES6+)
• Strong experience in React Native
• Proficiency in HTML5, CSS3, and Responsive Web Design
• Hands-on experience with MongoDB (schema design, indexing, querying)
• Working knowledge of Node.js (Intermediate — must be comfortable building and maintaining API modules independently)
• Experience with RESTful APIs and third-party integrations

AI-Assisted (Vibe Coding) Experience

• Hands-on experience using AI-powered development tools such as Cursor AI, Claude, GitHub Copilot, ChatGPT, or similar coding assistants.
• Ability to leverage AI tools for faster development, debugging, refactoring, code reviews, documentation, and productivity improvements.
• Strong understanding of AI-assisted software development workflows while maintaining high code quality, security, and engineering standards — including the judgment to know when AI-generated code needs manual review or rework.

Mobile App Deployment

• Experience generating production-ready Android and iOS builds.
• Hands-on experience publishing and maintaining applications on the Google Play Store and Apple App Store.
• Familiarity with app signing, provisioning profiles, certificates, store compliance, and release management.
• Prior first-hand experience with iOS submission is strongly preferred, given the setup time typically required for certificates and provisioning profiles.
