Zero-Downtime Migration
Personal home project leading complete network infrastructure migration from Layer 3 switch with EIGRP/OSPF to OPNsense gateway. Eliminated routing loops causing network instability, implemented 6-VLAN segmentation for security isolation (Kids, Family, IoT/Cameras, Guests, Management), and achieved 90% completion with only 30 seconds of downtime during trunk port conversion. Prepared foundation for 802.1X authentication and content filtering with Active Directory integration.

Network Optimization
Personal home project implementing automated SSL certificate management on OPNsense firewall using Cloudflare API integration. Configured ACME client for Let's Encrypt wildcard certificates (*.ruhigita.com) using DNS-01 challenge validation. Optimized network performance through FreeBSD system tunables, achieving 738 Mbit/s throughput. Documented complete setup including API token configuration, certificate automation, and troubleshooting procedures.
