Dominican RepublicWhat I'm looking for
He administrado infraestructura de red para múltiples clientes a través de Fiverr, trabajando con VPN, DNS, LAN/WLAN, evaluaciones de vulnerabilidades, OSINT y automatización en servidores Linux.
En mi proyecto de datacenter híbrido de PUCMM diseñé una arquitectura con Proxmox VE 8.4 y Azure IaaS, incorporando Zabbix 7.0 para detectar fallas en menos de tres minutos y conectividad mediante WireGuard VPN, túnel SSH inverso y Azure Bastion.
También documenté tres incidentes en un laboratorio SOC con Wazuh SIEM y MITRE ATT&CK: fuerza bruta, pentesting de CVE-2011-2523 y una simulación de ransomware con 19 alertas FIM.
Complemento mi trabajo en redes y ciberseguridad con proyectos de datos, incluyendo Meat Signal, donde integré FastAPI, BigQuery, Power BI y Pentaho Spoon para crear un pipeline ETL y una señal de compra B2B.
