Message

At Mercado Livre Brasil, I work as a System Engineer. Before that, at Azion, I was involved in planning and maintaining a highly distributed infrastructure.

At Azion, I worked on global-scale network operations and support, multivendor equipment, peerings, and Points of Presence. I also designed and deployed high-availability environments and configured firewalls and IPS sensors.

At NIC.br, I supported infrastructure, networks, and systems for IX.br (PTT.br), and earlier contributed to participant support and network troubleshooting. I focus on Linux, routing, network automation, and security, and enjoy creating technical documentation and sharing knowledge.
