Project History
eCommerce Platform with Advanced Analytics
I designed the product catalog to support search, filtering, and categorization, and implemented secure user authentication and authorization. The shopping cart and order processing system integrates a simulated payment gateway. I also created real-time sales dashboards with interactive charts and reports generated using Highcharts, offering valuable insights for decision-making.
The platform includes an admin panel for managing products, users, orders, and analytics, all supported by a RESTful API design to ensure a scalable microservices architecture. To streamline development and deployment, I automated CI/CD pipelines with Azure DevOps and containerized the application using Docker for portability. This project highlights my proficiency in end-to-end web development, clean architecture, scalability, and data-driven decision-making.
