Description

I am an IT consultant specializing in cybersecurity, systems administration, and the integration of AI solutions for businesses. I help SMEs and organizations improve the security, stability, and efficiency of their technological infrastructure, combining practical experience in corporate environments with a clear focus on results.

I have over 11 years of experience in systems administration and currently work as a cybersecurity manager in the hotel sector, managing Windows environments, Active Directory, GPO, VMware, networks, firewalls, VPNs, backups, remote access, technical documentation, and user support.

I can assist you with projects such as security reviews, system hardening, improvement of password policies, implementation of managers like Bitwarden, secure access configuration, procedure documentation, internal audits, business continuity, task automation, and deployment of corporate tools.

I can also collaborate on business AI projects, especially in proof-of-concept with private assistants, RAG on internal documentation, Open WebUI, Ollama, automations with n8n, and solutions designed to improve processes without exposing sensitive information.

My goal is to provide a practical vision: realistic, secure, and maintainable solutions, adapted to the size and needs of each company.
