Black Hair Konfidence

E-commerce marketplace with Stripe payments, admin dashboard, Cloudinary media, and Angular/Material UI.

Black Hair Konfidence

Overview

Black Hair Konfidence is a full-stack e-commerce marketplace built with Angular and Material UI on the frontend, NestJS on the backend, and PostgreSQL for data persistence. The platform features a rich admin dashboard with Stripe payment integration, Cloudinary-based media management, product catalog with categories and featured items, order management with status tracking, and a customer-facing storefront. The backend uses TypeORM, JWT authentication, role-based access control, and includes Swagger API documentation.

Challenge

The natural hair care community lacked a dedicated, well-designed platform with robust admin tools, payment processing, and media management for managing a growing product catalog.
