ASIR Student | Networking | Infrastructure | Security | Automation
I'm an ASIR student focused on networking, systems administration and cybersecurity, with hands-on experience working with network infrastructure and building cybersecurity labs, security tools and automation projects.
My approach is practical:
Build → Test → Troubleshoot → Secure → Document
- Network infrastructure and security
- Firewalls, VLANs and network segmentation
- Linux and Windows administration
- Blue Team / Purple Team
- SIEM and security monitoring
- Python automation
- Virtualization and homelab infrastructure
Based in Barcelona, Spain and open to part-time opportunities in IT infrastructure, networking, systems and cybersecurity.
