I’m a Ukrainian student and a unix/linux & open-source enthusiast, trying to get into cybersecurity, gain some practical skills.

My interests are:

• Cybersecurity
• Low-level programming: C, Rust, Zig, C++, Assembly
• Reverse engineering (IDA, Ghidra, NinjaBinary)
• Electrical engineering
• PCB designing (KiCad — yet to try)
• Self-hosting
• A little bit of 3D
• A little bit of game development

Self-hosting

I have a Raspberry Pi 5 with 4GB of RAM running DietPi and nixpkgs (I hate outdated Debian packages).

Currently hosting a bunch of stuff on it via Docker containers with help of desec.io.

Some project I have

Facinus

Since our college switched from Windows to Ubuntu, I had a cool idea to remotely control my classroom PCs.

I discovered gsocket.io and started developing a tool that deploys a local web admin panel to collect logs from connected clients.

I used an Ubuntu VM in QEMU and Bash scripted everything with some help of AI.

Cybersecurity

I’ve been into cybersecurity for about 2 years now. I started with the normie setup — Kali Linux dual-booted next to Windows, learning through trial and error.

Eventually I spent more time on Linux, moved to KDE, configured everything myself, riced my terminal. Later switched to Arch and Hyprland.

I still have lots to learn, and I’d love to document all the tools and techniques I come across.

HackTheBox

HTB gave me that initial hands-on boost I needed.As of right now I’ve solved more than 50 boxes (3 of them “Insane”: DarkCorp, Mist, and MassGarden).

Even though I sometimes rely on writeups and walkthroughs, I learn a lot from the infrastructure behind each box.

I’m not sure if using writeups spoils the learning, but for now it gives me clarity and saves time. I aim to shift toward solving without spoilers in the future.

Russian targets

I’m Ukrainian, so I practice skills on real russian infrastructure. It’s morally right and beneficial, especially in these times.

Bug bounty

Bug bounty is fascinating — legally hacking in-scope apps and possibly earning money.

But as a beginner, it’s tough. Recon is time-consuming, and rewards don’t always justify the effort unless you're really skilled.

I’ve tried a few programs but haven't found any serious vulnerabilities yet. I plan to shift my focus toward learning specific attack techniques and improving my skills first.

My setup

I use Arch Linux on a laptop — it just works and lets me get things done. I run Hyprland and use NVChad for Neovim.

Here’s my fastfetch output:
