Full-Stack MERN Developer Needed – Build Web App with OpenAI API Integration

We’re looking for an experienced Full-Stack MERN Developer to build a modern, responsive web application that integrates OpenAI’s API (e.g., GPT models) for intelligent features such as text generation, summarization, or chat-like interactions. 🎯 Project Overview You will develop a complete MERN stack application (MongoDB, Express.js, React Native, Node.js) with secure backend logic, a clean UI, and seamless integration of OpenAI APIs to power core AI-driven functionality. 🔧 Key Responsibilities Design and implement RESTful APIs using Node.js/Express. Build responsive, interactive front-end components with React.js. Integrate OpenAI API (text completion, chat, embeddings, etc.) securely on the backend. Set up MongoDB schemas and handle data storage/retrieval for user sessions, prompts, and outputs. Implement authentication (e.g., JWT, OAuth) and role-based access if needed. Optimize performance, handle errors, and ensure API rate-limiting and usage monitoring. Deploy the app to a cloud platform (e.g., AWS, Render, Vercel, or similar). ✅ Required Skills & Experience 5+ years of professional experience with the MERN stack. Proven experience integrating third-party APIs, especially OpenAI or similar LLM APIs. Strong understanding of security best practices (API key management, environment variables, CORS, etc.). Familiarity with Git, CI/CD pipelines, and cloud deployment. Ability to write clean, documented, and maintainable code. 📦 Deliverables Fully functional MERN application with OpenAI integration. Source code hosted on GitHub/GitLab with clear setup instructions. Basic documentation for API endpoints and environment configuration. Deployed demo link for testing. 🌟 Nice to Have Experience with streaming responses (Server-Sent Events or WebSockets) for real-time AI output. Knowledge of prompt engineering or fine-tuning LLM behavior. Previous work on AI-powered SaaS or productivity tools. ❓ Screening Question Please share one link to a live MERN project where you integrated an AI/LLM API (like OpenAI), and briefly describe your role and the biggest technical challenge you solved.
