I build from the kernel up to the UI.

(01)Hi, I’m Daniel

I build things from the kernel up to the UI: XDP filters, Go backends, desktop apps and Telegram Mini Apps. In production, used by real people.

(03)About

I'm Daniel, Daniil Tenishev on paper. 18, first year of Software Engineering at ITMO, group M3105, class of 2030. I live in Pushkin and ride into Saint Petersburg every day.

Right now
  • Studying at ITMO
  • Working as a developer alongside uni
  • Building Omniflow, my own VPN service
  • Open to internships and offers
Character
  • hard-working
  • easy-going
  • open-minded
  • self-confident

Friends say that about me. I always want to know how things work inside. That is how I end up writing engines, protocols and a passport-chip reader. My strongest skill is solving problems.

Love & hate

love +

  • coding
  • real guns at the range
  • travelling

hate −

  • early alarms
  • fixing bugs at 3 a.m.
  • (I still do it.)
Hobbies

Travelling and games: 134 on Steam, mostly the kind where you build factories. If I weren't a programmer, I'd be a pilot.

LarpGuard

Cloudflare.But self-hosted.

A bot filter in front of Traefik that reads every layer of a connection and asks one question: does this stack match the browser it claims to be?

LarpGuard console: live request stream

0proxy lists. RTT does the work.

TCP SYN, JA4/JA4T/JA4H, HTTP/2 and QUIC fingerprints scored into human, suspicious, bot and verified_bot

Proxy detection from the RTT gap between TCP and the TLS 1.3 handshake, without proxy lists

XDP/eBPF prefilter with its own loader; gradient-boosting inference in C++ in microseconds

Omniflow

A whole VPN business.One open platform.

My own VPN business, turned into an open product: Telegram bot, subscriptions, payments, support, marketing and an admin panel on top of Remnawave, without owning Xray.

Tether

adb.Without the text file.

Every Android developer keeps a text file of adb commands. Tether puts all of it in one quiet, keyboard-first window.

Tether: device overview with battery, storage, memory and CPU
Tether: the ⌘K command palette
⌘Kcommand palette for everything
QRWi-Fi pairing
OTAsigned updates
Rustcore on Tauri, talks the adb protocol

Screen mirroring with audio and recording, a file manager, APK installs to many devices at once

Logcat with crash detection, multi-tab shell, Wi-Fi pairing by QR, performance graphs

Talks to the adb server over its protocol instead of parsing the CLI; ⌘K palette, signed OTA updates

Install with Homebrew ›

m3105.ru

My group's site.The whole year opens it.

Deadlines, labs, lecture notes, quizzes and lab-defence sign-ups in one place. The whole year uses it.

Notes write themselves.

MDX notes with formulas, generated from voice recordings of lectures: transcript, diagrams and a quiz.

/cpp checks your code.

A Monaco editor where clang-tidy and clang-format check it against Google Style.

Works in the metro.

A PWA: notes open with no signal. Calendar with week parity and an ICS feed.

Real range, real guns.

Shooting real guns at the range is one of my favourite ways to switch off.
