About

Cybersecurity student and software engineer focused on systems programming, Windows internals, security research, and building practical applications.

I enjoy working across multiple abstraction layers — from kernel-mode components and native C/C++ to .NET desktop applications, Android, networking and modern web interfaces.

  • 🎓 Studying Cybersecurity at Khmelnytskyi National University
  • ⚙️ Exploring Windows internals, kernel development and low-level telemetry
  • 🛡️ Working with security research, reverse engineering and system observability
  • 🖥️ Building desktop software with C#, .NET and Avalonia
  • 🌐 Developing web applications with TypeScript, React and modern web tooling
  • 🐧 Daily-driving and experimenting with Windows and Linux environments
