Backend API: FastAPI (Python), SQLModel, Uvicorn
Database: PostgreSQL (Relational schema designed for scale)
Integrations: PayFast, JazzCash, EasyPaisa (Multi-channel payment gateways)
SEO & Crawling: Dynamically generated XML sitemaps, semantic HTML, and custom crawlers configuration
🌟 Key Features Developed
1. 🛍️ Customer Experience (Next.js)
Dynamic Catalog & Advanced Filters: Lightning-fast searching, category navigation, and attribute-based sorting.
Optimized Product Detail Pages (PDP): Detailed specification grids, dynamic pricing adjustments, and full content metrics formatter.
Instant SEO Routing: Real-time generation of sitemap.xml and robots.txt ensuring automatic indexing of thousands of products by Google.
2. 💼 Vendor & Admin Control Rooms
Unified Dashboard: Live reports on sales statistics, commissions, returns, and order fulfillment progress.

Impressive full-stack build; scalable architecture, strong vendor controls, and thoughtful payment and SEO integrations make this marketplace feel truly production-ready. 🚀
Título del Proyecto:
Secure Full-Stack Management System (RBAC & Advanced Auth)
El Reto:
Desarrollar una plataforma de gestión de contenidos (catálogo de libros) que requería un sistema de permisos granular, mitigación de vulnerabilidades web (inyecciones, ReDoS) y una autenticación a prueba de secuestros de sesión.
La Solución:
Construí una aplicación Full-Stack (React/Node.js) implementando un sistema de Control de Acceso Basado en Roles (RBAC) para Usuarios, Moderadores y Administradores. Diseñé un flujo de autenticación JWT robusto de cero, con rotación de tokens y detección de reuso para maximizar la seguridad del usuario sin perjudicar la experiencia (UX).
Puntos Clave del Código:
Autenticación de grado corporativo: Implementación de Access Tokens en memoria (15 min) + Refresh Tokens (HttpOnly, 7 días) con rotación automática y revocación de sesión ante detección de reuso.
Seguridad Defensiva: Middlewares personalizados para validación genérica, manejo centralizado de errores y mitigación activa de ataques ReDoS e inyección NoSQL.
Arquitectura de Datos Backend: Gestión de base de datos en MongoDB con Mongoose, implementando flujos de soft/hard delete, filtros de búsqueda avanzados y fallback a memoria local.
Frontend Resiliente: Manejo de estado global con React Context y recarga silenciosa de tokens (silent refresh) interceptando las peticiones sin que el usuario note interrupciones.
Tech Stack:
Node.js (Express 5) | MongoDB & Mongoose | React & Vite | JWT Auth | Resend (Transaccional)
