I’m a systems engineer with hands-on experience in Linux servers, VoIP systems, and cloud-based infrastructure. I specialize in setting up, managing, and troubleshooting communication platforms like Issabel and providing reliable IPTSP services for businesses. I have strong experience working with virtualization (Proxmox), server administration, and maintaining production environments. I also work with email systems including cPanel, Zimbra, and Postfix—handling setup, migration, DNS configuration, and delivery troubleshooting. My approach is simple: deliver stable, secure, and scalable solutions that actually work in real-world business environments. I focus on performance, uptime, and clean configurations so you don’t face issues later. Currently, I’m expanding my skills in DevOps and cloud engineering, including automation with Python and Bash, to provide more efficient and modern solutions. If you need help with VoIP setup, server management, email systems, or cloud infrastructure—I’m here to help.
