Hello
My profile is of a senior systems architect. I have 20 years of experience in systems and network administration, designing and implementing systems for both big scale customers and medium to small companies
I have been working on ISP for more than 10 years, doing both system and network administration.
In system administration, I am specifically strong in Linux technologies, and all the application stack. I have a strong background in email platforms, hosting and clustering solutions, including of course all the stack used for load balancing, high availability and publishing techniques.
In network administration, I have worked with Cisco, Avaya and Dell switching technologies. As for security, I have worked with Checkpoint, Sonicwall and lately Fortigate firewalls.
For the last years, I have focused strongly in Vmware virtualization, and integration with private/hybrid cloud in AWS/Azure cloud.
I have evolved to a consulting/architecture role, but still keeping intact my system administration and troubleshooting capabilities. I am able to produce architecture and design documents, as well as run the full implementation of the projects afterwards.
I am a true professional in IT who has worked both for small and big customers, so I have a right view of the differences when dealing with them
