Projects (Recent)

Network Traffic Analysis and Protocol Engineering

Developed proxy cache server for network optimization using tcpdump for packet capture, Wireshark/tshark for traffic analysis, and netcat for connection testing. Implemented network troubleshooting using ping, traceroute, nmap for port scanning, and dig for DNS resolution analysis.

KVM/QEMU GPU Passthrough with Kernel Configuration

Configured KVM/QEMU virtualization with VGA passthrough requiring kernel parameter modification via GRUB configuration, VFIO driver binding using modprobe and kernel modules, and hardware enablement. Utilized systemd-boot, mkinitcpio for initramfs generation, and dmesg for kernel debugging during hardware configuration experiments.
