Throughout my career, I have collaborated on international projects across Brussels, Madrid, Mallorca, and Barcelona, working with industry leaders such as Cisco, Nortel, Telefónica, SITA, etc. These roles have honed my skills in managing diverse teams, leading global network deployments, and ensuring high availability and security for complex infrastructures. I have enjoyed working in large and diverse teams, both leading and following.

In my most recent role as a Data Center NetworkOps and Security Specialist at SITA for Aircraft, I was instrumental in maintaining the security and reliability of global data center operations. Leveraging advanced Cisco and Fortinet solutions, I optimized routing protocols, configured VPNs, and proactively monitored systems, ensuring uninterrupted service for international stakeholders. These experiences have sharpened my ability to troubleshoot and deliver mission-critical solutions under pressure.
