I design and run the connective tissue of small-to-mid business IT — routing, site-to-site VPNs, virtualization and hosting — built through years of hands-on production work rather than a classroom.
MikroTik, VLAN, DHCP, NAT, firewall rules, port forwarding, Wi-Fi, site-to-site networking, Cisco fundamentals.
WireGuard, IPsec, GRE, SSTP, L2TP, reverse tunnels, Shadowsocks, Outline, V2Ray/X-UI, WSS/TCP multiplexing, backhaul.
Linux, Windows Server, VMware ESXi, VPS administration, DNS, Cloudflare.
WHM/cPanel, WordPress, SSL, CSF/LFD, Fail2Ban, backup/restore, incident response.
Issabel, SIP trunks, extensions, inbound/outbound routes, IVR, call recording.
Bash, Python, PowerShell, cron, backup scripting, VPN tooling, Telegram bot development.
Connected geographically separate LANs over different internet connections, enabling cross-site communication and RDP over the routed environment.
Deployed business connectivity with WireGuard, IPsec, GRE, SSTP, L2TP and multiple reverse/VPS tunneling methods.
Recovered server-hosted email data from independently designed off-server backups after validating backup integrity; subsequently strengthened firewall and anti-spam controls and user guidance.
Maintained patched and monitored WHM/cPanel infrastructure during high-volume attack activity and investigated service disruption with no confirmed compromise.
