impl Developer for Vadim {
    const ALIASES: &[&str] = &["VAI_PROG", "VAI_Programmer", "VAI", "VOLT"];

    fn role(&self)      -> &str { "backend & systems engineer, builder of fast, slightly unhinged things" }
    fn known_for(&self) -> Vec<&str> { vec!["Hatsune Miku editor themes", "Any Tech Architect", "A CAT", "FilianWIKI"] }
    fn current(&self)   -> &str { "turning a billion on-the-fly ideas into running services" }
}

I write code that is practical and a little playful: backend services, bots that genuinely help people, and systems where performance matters. Rust is home; Python and TypeScript keep up with my thinking, and C++ / Cython come out when the profiler insists. Between commits I write short books, novellas and fanfics.

Why Rust first? The borrow checker is the cheapest code reviewer I have ever hired: it costs nothing and never sleeps. C-grade speed, memory safety the compiler enforces, fearless concurrency and one binary for any box in the fleet. This profile is drawn by one.

HatsuneMikuEditorTheme: one palette contract, four looks, six editors (VS Code, Zed, JetBrains, Neovim, Sublime Text, Notepad++). And now the browser: a Miku new tab for Chromium, Firefox, Zen and Firefox for Android, with four layouts, widgets and Helium style !bangs, plus window colors for Chromium and a Zen mod. This whole profile is painted in its Miku Dark.

architect.vai-rice.space: obfuscation configs with every number explained. Two engines, AmneziaWG 3.1 and XRay REALITY, and everything is computed in your browser, so keys and configs never leave it.

awg-containers-and-tools, Architect's companion: self-hosted AmneziaWG for every generation from 1.0 to 3.1 as small images, a tunnel-only resolver, and awg-tool, a Rust CLI that installs servers over SSH, issues peers and rotates obfuscation.

NotAnOtherVTUBERwiki: my wiki engine for fan communities. Rust and Axum, Markdown first, fast on a Raspberry Pi, works with JavaScript off. It runs FilianWIKI.

the-wall.vai-rice.space: a Win95-styled extension for The Wall, the Snackers' 6000 × 4200 pixel canvas. Template overlay, clans, shared templates and bot alerts.

kumir3-core: the classroom language Kumir, rebuilt in Rust. Interpreter, TUI and a compiler to Rust and WASM, and yes, the Robot still paints corridors.

Aethelgard TQ-1.58 HVRL is an architecture for a low-bit agentic reasoning model with verifiable training, hierarchical reinforcement learning and a specialization in software engineering. Its weights live in ternary space {-1, 0, +1}, about 1.58 bits each, hence the name.

Why ternary? A weight that can only be −1, 0 or +1 turns most multiplications into additions and a zero into nothing at all. Inference gets cheap enough for my own fleet instead of a rented datacenter, if the model trains without falling off the accuracy cliff. That "if" is the research.

I am part of the Snackers, the community around the VTuber Filian, and I build things for it:

• 📖 FilianWIKI: the wiki for Snackers HQ+, Snackers RU and every snacker in the world, on my own engine. Open beta: sign in with Discord or Telegram and start editing.
• 💗 Filian.ru: the home of Snackers RU, the Russian-speaking community.
• 🧱 The Wall Dev: tools for The Wall, our shared pixel canvas.

🎁 Snackers RU gifted me a Hatsune Miku figure. Thank you, Snackers RU! 💙

_{All of the above are fan projects: unofficial, and not part of Filian's ARG.}

Everything here comes fresh from three forges at once: GitHub, Codeberg and my own git.vai-rice.space. Mirrors are deduplicated, so code is counted once while every platform's stars still count.

Most of what I run lives at home, in a homelab of laptops: two of them work as servers on Arch and NixOS, and my main laptop dual boots Windows 11 and Arch Linux. Laptops make a surprisingly good homelab: they sip power, carry their own UPS (the battery) and come with a screen and a keyboard for the day SSH says no.

Out in the world, VPS on Arch, NixOS, Ubuntu and Debian hold the edge.

Primary address: vadim@vai-rice.space. I read mail constantly. To land in the right lane, use the matching alias (+tag sub-addressing works too):

The fan addresses are the same ones printed on filian.wiki, snackers.wiki and filian.ru. Every one of them lands with me, a human.
