Fashionboost: sistema de gestão e fidelização para lojas de moda

Abstract

This work aims to develop a SaaS (Software as a Service) system for small and medium- sized fashion store owners, called FashionBoost. The proposal arises from the observation that small retailers in the fashion sector generally do not have access to affordable customer management and loyalty tools, such as CRM systems and loyalty programs. The system was developed with NestJS and TypeScript on the back-end, TypeORM and PostgreSQL on the persistence layer, and Next.js 15 with Tailwind CSS v4 on the front-end. The adopted architecture follows the multi-tenant model, in which each retailer operates in a completely isolated environment within the same platform. Key implemented features include: product, inventory and category management; sales recording with discount coupon application; a loyalty program with point accumulation and automatic tier progression; and an artificial intelligence dashboard integrated with the Groq API using the Llama 3.3 70B model. The results demonstrate that FashionBoost is capable of supporting operational management and customer loyalty in independent fashion stores, answering the proposed research question with a viable and accessible technical solution.
