Red Team & systems administration. I build offensive tooling (Mythic C2 agents, Burp extensions, intercepting proxies, loaders, bug-bounty automation), I audit and harden Windows/Linux infrastructure, and I document what I break. On the side: Rust (engines, games), embedded (ESP32, SBCs, IoT, BLE), KiCad, drones — and a real appetite for operating-system internals.

Offensive / Red Team

  • C2 & implant development
  • Burp Suite extensions, fuzzing, crawling
  • Loaders / payloads (Windows & Linux)
  • Bug bounty — tooling & automation
  • Web: SQLi, web shells, recon

Systems & infra

  • Windows Server, Active Directory, GPO
  • Linux (Debian/Ubuntu/RHEL) — hardening, scripting
  • Networking: segmentation, VLAN, firewall, VPN, DNS
  • Proxmox VE, Docker / Compose, TLS reverse proxy

Defensive & ops

  • AD hardening (tiering, LAPS, bastion)
  • Logging, SIEM, monitoring (Prometheus/Grafana/Zabbix)
  • 3-2-1 backups, DR, restore testing

Dev & internals

  • Go, Rust, Python, Bash, PowerShell, ASM
  • OS internals (Linux, Windows, Android): rings & privilege levels, driver / kernel-module development, ABI & syscalls
  • ESP32, SBCs, IoT, BLE & D-Bus, KiCad, drones
