About me
I'm an IT specialist based in Brazil (originally from Argentina), focused on infrastructure, network security, and business websites for small and medium companies. My background is in technical support and network administration — I now build and manage the systems businesses rely on daily: servers, firewalls, backups, and the websites that represent them online. I work with reliable tools (React/Next.js, Fortinet, Veeam, Proxmox) and clear communication. Not sure which package fits? Message me before ordering.
