The longer version

A bit more about me

I got into computers early and never really stopped — first taking them apart and fixing them, then writing software, then learning how both of those break. Today I'm a fourth-year Information Security student in Chelyabinsk, and most of my time goes to two things I genuinely run myself.

One half is building. I keep two products in production — an AI platform and a licensed security product — and I own the whole technical side, from the backend and the servers to the desktop client and the release pipeline. The other half is breaking: I audit my own systems, work out how they'd be attacked, and keep the edge sharp on pentest labs and vulnerable machines. I don't think you've really secured something until you've tried to break it yourself.

Along the way I started a small web studio, led a dev team and worked the floor as a club administrator — so I know infrastructure from the terminal and from the moment a real person in front of me just needs it to work. I like making things that are reliable, clear and a little bit hand-made. This whole site — and this portrait — were put together by hand.

Skills

What I actually use, grouped the way I think about it. Everything here has been through a real project — a product in production, a test stand or a machine taken apart.

Stands and research

Portable hardened stand

2026

A pocket router nothing leaks past

A pocket router hides all traffic from the attached device in an obfuscated tunnel and lets nothing leak past it. The uplink is a phone over USB; there is deliberately no SIM in the router.

A hardened, isolated Windows 10 in VirtualBox

All DNS is forced through Cloudflare DoH, plain DNS is blocked, host-to-guest channels are closed. Threat model, deployment scripts, isolation checks.

Local LLM agent

2026

The expensive hypothesis was wrong; the cheap check was right

A local model running as an agent in opencode produced 1 token per second. Trying different quantisations changed nothing: the system had no NVIDIA driver and the GPU was computing through Vulkan. After the driver — 16 tokens per second and working tool-calling.

Experience

2026 — present

Asterio — co-owner, Backend / DevOps

One of two developers behind the AI platform: I lead the site, the REST API and the server side — FastAPI under Uvicorn in Docker, PostgreSQL behind a connection pool, Redis, Nginx with Let's Encrypt, a three-contour production topology, zero-downtime deploy with rollback. In active development.

2025 — present

VANTAGE GUARDIAN — co-owner · network protection for clubs

Client and server side of a network-protection product for gaming clubs. It runs in the Colizeum club network — that's where the collaboration with Colizeum is now: three clubs, 127 machines, nodes in Frankfurt.

2025 — 2026

Constructa — founder · website studio

My own startup: a small website studio built on one principle — a direct line to the developer, service and unusual projects, run by a close and trusted team. The foundation was ready, but as students with no funding I couldn't carry it then. Good experience and an honest conclusion.

2025 — 2026

Colizeum Cyber Sport Arena — administrator

Ran the club and its machines at a high service bar: client support, diagnostics and repair, workstation setup and optimization. Now in the staff reserve, covering shifts when needed. This is where the trust that turned into the VANTAGE collaboration was earned.

2025

KiberPride — administrator

Ran the floor of a gaming club: guests and bookings, the till and attendance, workstation setup and first-line troubleshooting.

2023 — 2025

BrainFox — lead developer

Led web development for about two years: site architecture and client solutions, requirements gathering, coordinating the team and setting standards, a knowledge base and onboarding.

Education

2023 — 2027

Chelyabinsk Radio Engineering College

Penetration testing, system administration, information-security basics, Python and C# development, GameDev — the college's hands-on courses alongside the main track.

Self-study

TryHackMe and Hack The Box, red team and blue team. Pentesting pulls me in the most: you see straight away whether the reasoning holds.
