Proxmox Disaster Recovery and Network Segmentation Design
Designed a security-first Proxmox architecture separating VoIP, web, database, and management traffic with deny-by-default firewall policies. The solution uses HAProxy for web services, WireGuard for secure site-to-site connectivity, Proxmox Backup Server for off-site backups, and a standalone Contabo host for failover of critical PBX and escrow workloads.

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)
