I help businesses design, troubleshoot, and secure reliable networks so operations stay stable and risk stays low. I’m a hands-on Network & Security Engineer with 9+ years of experience delivering real-world solutions across Cisco, MikroTik, Fortinet, pfSense, VPNs, and monitoring.
I focus on scalable, documented, long-term fixes (not temporary patches), and I communicate clearly throughout the project.
What I can help you with
• Network Design & Troubleshooting (LAN/WAN/Wi‑Fi): routing, switching, VLANs, inter-VLAN routing, performance tuning, site-to-site connectivity
• Firewall Setup & Hardening: Fortinet / pfSense / Cisco ASA, NAT, security policies, segmentation, best practices
• VPN Setup: IPsec / SSL / Site-to-Site / Remote Access, user access control, multi-site tunnels, secure remote work
• MikroTik RouterOS Services: routing, firewall, bandwidth/QoS shaping, ISP/WISP setups, wireless optimization, network troubleshooting
• Server & Virtualization Support: Windows/Linux administration, VMware / Hyper‑V (support, integration, migrations)
• Cloud Support: AWS / Google Cloud (GCP) connectivity, migration support, hybrid networking
• Monitoring & Alerts: PRTG / Zabbix, dashboards, alerts, proactive issue detection
Example results delivered
• Ransomware recovery + security hardening: recovered 91% of encrypted files and implemented protective controls
• Multi-site network (50+ employees): reduced downtime 87% and saved $15,000/year through optimized architecture
• Secure VPN rollout (3 countries): enabled remote work for 30+ users across multiple locations
How I work
• Quick assessment → clear plan → controlled changes → testing → full documentation
• Secure-by-default approach and clean, maintainable configurations
• Available for one-time projects, ongoing managed services, and urgent troubleshooting
