Afanasev

Seasoned Systems Administrator & DevOps Engineer I don't just install software; I build resilient, high-availability infrastructures. With a strong background in large-scale healthcare systems, I specialize in mission-critical environments where downtime is not an option. I have a proven track record of stabilizing failing systems and optimizing database performance under heavy loads. Core Competencies: Infrastructure: Linux (Debian/Ubuntu/CentOS), Windows Server (AD, GPO), Docker, Proxmox VE. Advanced Networking: Tunneling protocols (WireGuard, OpenVPN), multi-layered network security, and complex NAT traversal for restricted environments (MikroTik, Cisco). DB Optimization: MySQL (Master-Slave replication, deadlock resolution, query profiling, slow log analysis). Remote Ops: Secure RDP/SSH management, AnyDesk, troubleshooting 1C & PACS/RIS medical software. If you need someone to fix a "broken" server that others gave up on — I'm your guy.
