Jahongir Qasimbayev

Tashkent, Uzbekistan

Cybersecurity specialist and system administrator with hands-on experience in Linux administration, network security, virtualization, and full-stack software development.

Currently studying Computer/Information Technology Administration at the Academic Lyceum of TUIT and completing the cybersecurity program at School 21 (42 Network). I build and administer complex systems from bare metal, design security-monitoring platforms, and simulate enterprise network environments end to end.

Projects

Server Sentinel

featured

AI-powered security monitoring SaaS: a multi-agent intrusion detection and automated incident response platform for the Uzbekistan/CIS market. Nine microservices in a pnpm monorepo, a safe attack-simulation mode (is_simulated), and a four-tier pricing model — built with graceful degradation as a first-class requirement.

ML-Based Network Intrusion Detection System

featured

Diploma thesis. A multi-segment virtual lab in GNS3 simulating a realistic enterprise network (Debian VMs + Cisco IOS router). Generated labeled datasets via ICMP flood, port-scan and SSH brute-force simulations, then trained and evaluated an ML classifier on the captured traffic.

Virtualization & GPU Passthrough Lab

featured

A Windows 11 VM on Arch Linux with full NVIDIA GPU passthrough via KVM/QEMU. Looking Glass for low-latency framebuffer sharing without a second monitor; careful IOMMU grouping, PCI isolation and device binding for stable passthrough.

Arch Linux Workstation & Desktop Environment

A fully customised Arch Linux environment built from bare metal: services, permissions, the PipeWire audio stack, Bluetooth, GPU drivers and networking — running both KDE Plasma and Hyprland, with TTY recovery and conflict resolution along the way.
