A scalable and modular e-commerce platform built using a microservices architecture. The system is designed to handle core e-commerce functionalities such as product management, cart operations, order processing, payment integration, and user management through independently deployable backend services.

The project demonstrates real-world backend engineering concepts including RESTful APIs, database design, asynchronous communication, scalability, service abstraction, caching, payment gateway integration, and microservices-based system design using Spring Boot and related technologies.

• Registration: Allow users to register via email or social media profiles.
• Login: Secure user login with credentials.
• Profile Management: Enable users to view and edit their profiles.
• Password Reset: Allow password resets through secure email links.

• Browsing: Users can browse products by category.
• Product Details: Product pages include images, descriptions, specifications, and more.
• Search: Provide search functionality with keyword-based queries.

• Add to Cart: Users can add products to their cart.
• Cart Review: View selected items with price, quantity, and totals.
• Checkout: Seamless process to finalize purchases, including delivery details and payment options.

• Order Confirmation: Confirm orders with details after purchase.
• Order History: Allow users to view past orders.
• Order Tracking: Provide delivery status tracking.

• Multiple Payment Options: Support credit/debit cards, online banking, and other methods.
• Secure Transactions: Ensure secure payment handling.
• Payment Receipt: Generate receipts for successful payments.

• Secure Authentication: Protect user data during login and active sessions.
• Session Management: Allow users to stay logged in until they log out or after a specified duration.

1️⃣ Load Balancers (LB): Distribute traffic across servers for high availability (e.g., AWS ELB).

2️⃣ API Gateway: Entry point for routing requests, managing rate limits, and handling authentication (e.g., Kong).

3️⃣ Microservices: Separate services for modular and scalable architecture.

4️⃣ Databases: MySQL and MongoDB for structured and unstructured data.

5️⃣ Message Broker (Kafka): Enable asynchronous inter-service communication.

6️⃣ Caching (Redis): Boost response times for frequently accessed data.

7️⃣ Search & Analytics (Elasticsearch): Efficient product searches with advanced capabilities.

1️⃣ User logs in and searches for a product.

2️⃣ Request passes through the Load Balancer to the API Gateway.

3️⃣ API Gateway routes the search request to the Product Catalog Service.

4️⃣ Product Catalog Service queries Elasticsearch for results.

1️⃣ User adds a product to the cart.

2️⃣ Cart Service stores the item in MongoDB and produces a Kafka message.

1️⃣ User checks out.

2️⃣ Order Management Service processes the order and sends a Kafka message.

3️⃣ Payment Service consumes the message to handle payment.
