I needed to demonstrate full-stack MERN stack expertise by building a complete e-commerce platform, but creating a secure, scalable system with payment processing, inventory management, and real-time features posed significant technical challenges.
Architect and develop a full-stack e-commerce platform using MERN stack (MongoDB, Express, React, Node.js) with secure payment integration, comprehensive admin dashboard, real-time inventory management, and optimal user experience that scales effectively.
Built full-stack MERN application with RESTful API architecture, implemented JWT-based user authentication and authorization, created product catalog with advanced filtering and search, developed shopping cart with persistent state and checkout process, integrated Stripe API for secure payment processing, built order management system with status tracking, created admin dashboard for product/order/user management, implemented real-time inventory management with stock updates, and added email notifications for order confirmations.
Successfully processed 1000+ test transactions securely, achieved sub-second API response times for product queries, reduced cart abandonment by 30% with improved UX, created scalable architecture supporting future growth, and delivered comprehensive admin tools improving operational efficiency.
Implementing secure payment processing required PCI compliance considerations, managing complex state across cart/products/user sessions, ensuring data consistency in inventory with concurrent orders, and optimizing database performance while maintaining real-time capabilities.
Solve complex technical challenges including secure payment processing, state management, data consistency, and performance optimization without compromising user experience or system reliability.
Designed secure payment flow with PCI compliance best practices, implemented Redux for managing complex state across cart/products/sessions, created database transactions and locking mechanisms for inventory consistency, optimized MongoDB queries with proper indexing, implemented efficient polling for real-time updates, and added comprehensive error handling and validation.
Ensured secure payment processing with no security incidents, successfully managed complex state without data loss, maintained data consistency even with concurrent orders, achieved optimal database performance, and provided seamless real-time user experience.
