Full-Stack Web App Development | React, Node.js, NestJS, MongoDBM J
I build scalable, end-to-end web applications using modern full-stack technologies including React, Node.js, NestJS, and MongoDB. From frontend design to backend logic and secure deployment, I deliver production-ready platforms optimized for performance, flexibility, and growth.
What's included
Full-Stack Application Architecture
A complete client-server setup with modular code, environment configs, and scalable structure using React (frontend) and NestJS (backend).
Responsive UI with React
Pixel-perfect, mobile-first UI with reusable components, styled with Tailwind, styled-components, or MUI — tested across all screen sizes.
REST or GraphQL APIs
Secure and scalable APIs using NestJS, built with controller-service-repository pattern. Includes validation, guards, and error handling.
MongoDB Database Design & Integration
Schema-first modeling using Mongoose or TypeORM with optimized relations, validation, and indexing for performance.
Authentication & Authorization
JWT or OAuth-based login system with role-based access control, password hashing, and secure refresh token workflows.
Real-Time Features (Optional)
Integration of WebSocket or Socket.io-based real-time updates for chats, notifications, or live dashboards.
Admin or Super Admin Panel (Optional)
Custom-built admin dashboard with CRUD features, filters, analytics, and audit trails — secure and scalable.
Deployment-Ready Setup
Production-ready Dockerized setup or CI/CD pipeline with environment configs for AWS, Vercel, or your preferred cloud provider.
Testing Suite (Frontend + Backend)
Automated tests using Jest, Playwright or Supertest to ensure stability and avoid regressions.
Documentation & Post-Delivery Support
