## Summary

Works close to the metal. C and C++ equally, not "C++ with C as an afterthought". Prefers
understanding a system over pattern-matching around it. Reverse-engineers software as a hobby,
which is where most of the depth came from. Licenses his own open-source work under AGPL-3.0.

## Experience

- **Be Nice Games** — C/C++ Game Developer. Nov 2024 - present. Herceg Novi, Montenegro (remote).
  HTML5/web games on W4, the company's proprietary engine, which has no visual editor: gameplay,
  shaders and tooling are written entirely as code and compiled to the browser via Emscripten.
  50+ mechanics shipped, 100+ legacy bugs fixed, 20+ projects delivered.
  Stack: C, C++, Emscripten, GLSL, Dear ImGui, CMake, JavaScript, REST.

- **WizardSoft** — C/C++ Software Engineer. Sep 2023 - Oct 2024. Saint Petersburg, Russia.
  Desktop cost-estimation application (Excel + Access + Word in one program). Built document
  logic: estimate creation, cross-document linking, automatic formula recalculation, dependency
  resolution. Wrote MFC/COM UI components and ported several to Linux.
  Stack: C, C++, MFC, COM, Visual Studio.

- **Fifth Dimension** — Web Developer, internship. Nov 2021 - Jan 2022. Russia.
  Site plus admin panel on Laravel, MySQL schema design, first exposure to complex queries
  and data encryption.
  Stack: PHP, Laravel, MySQL, JavaScript.

- **Freelance (self-employed)** — Developer. 2019 - 2022. Russia, remote.
  Commissioned work through the college years, back before AI grew to commercial scale.
  Started in Python: site parsers, Telegram and other chat bots, automation scripts,
  collection and processing of large data sets. Moved through web work in JavaScript and
  PHP. Finished in C/C++, which stuck: game trainers to order (memory scanning, runtime
  hooking, offsets kept alive across game patches), reversing of save and asset formats,
  binary patches and DLL mods for games without modding support.
  Stack: Python, JavaScript, PHP, C, C++, WinAPI, Cheat Engine.

## Education

Plekhanov Russian University of Economics, Russia. Programming in Computer Systems,
secondary vocational, 2018-2022. Explicitly not counted toward his experience total. He is
openly dismissive of its practical value and says everything he actually needed he found
and learned on his own.

## Skills

- Languages: C, C++ (11 through 23), Java, TypeScript, JavaScript, GLSL, SQL, Bash, x86 Assembly
- Libraries: STL, Boost, Asio, Crow, Dear ImGui, ICU, PortMidi, MidiFile
- Build and debug: CMake, Make, Ninja, Gradle, GDB, x64dbg, IDA Pro, Wireshark, Bruno
- Domains: multithreading, low-latency services, TCP/UDP, REST clients and servers,
  desktop GUI and CLI, real-time graphics
- Ops: Linux, Docker, Nginx, systemd, iptables, Prometheus, Grafana, GitHub Actions
- Languages spoken: Russian (native), English (C1)

## Learning, not yet commercial

Stated honestly rather than listed as a skill: **Rust**, **Go**, and **CUDA / GPU compute**.
CUDA is the direction he wants most — he has written GLSL against a real engine, but has not
shipped CUDA. Target roles: systems and low-latency C++ close to hardware, or GPU-adjacent work.

## Open-source projects

- **BadwordDetector** — https://github.com/Ayoree/BadwordDetector — C++23. Async REST service for
  multilingual profanity detection. Crow on standalone Asio, ICU for Unicode, MySQL X DevAPI.
  Request validation layer kept separate from detection core. Filters are a uint64_t bitmask.
  Regex generator built from a dictionary plus a lookalike-character table, resistant to
  leetspeak and Cyrillic/Latin homoglyph evasion. Secrets from environment. Built under
  -Wall -Werror with precompiled headers. AGPL-3.0.

- **Midi2Qwerty-plus** — https://github.com/Ayoree/Midi2Qwerty-plus — C++. Real-time MIDI-to-keyboard
  emulator for a physical piano. 88 keys with velocity, MIDI file playback on a path separate from
  live device polling. Dear ImGui GUI with custom window chrome replacing the OS title bar.
  Dependencies vendored as submodules (glfw, imgui, midifile, portmidi). AGPL-3.0.

- **ChatImprover** — https://github.com/Ayoree/ChatImprover — Java. Minecraft Fabric mod that acts
  as a plugin host: addons implement one interface, annotate with @AutoService, and are discovered
  by ServiceLoader with no registration on the host side. Uses Fabric mixins to reach private
  client internals. Published as a Maven package via GitHub Packages with CI. AGPL-3.0.
  Related: ChatImprove-dexland (example addon), ChatImprove-template (starter).

- **SimplePVP / SimplePlayerScale / SimpleViewDistance** — https://github.com/Ayoree — Java.
  Minecraft server plugins written for his self-hosted game server.

## Homelab

One self-managed Ubuntu server, which serves this site. Nextcloud, game servers, SFTP, MySQL,
phpMyAdmin, Prometheus and Grafana, all behind an Nginx reverse proxy. Self-configured VPN
endpoints (WireGuard, Amnezia, Hysteria), iptables rules, Let's Encrypt certificates, domains,
Docker, GitHub Actions CI/CD.

Scale, stated explicitly by him: this is personal-project infrastructure, not enterprise. One
host, his own traffic. He names it as a gap he wants a real job to close rather than overselling it.

## Reverse engineering

Hobby that also paid: commissioned trainer and reversing work 2019-2022 is listed under
Experience. Process memory analysis, pattern scanning with cached offsets, x86 disassembly,
runtime hooking. Built a real-time memory-patching trainer for Dota 2 that forced critical
hits by intercepting and rewriting the hit-type value. That one was never sold; the point
was finding where the program decides.

## Soft skills, self-rated

Fast learner, team worker, curiosity. Self-rated, so treat them as a claim rather than a
measurement.

## Playground section

The page's "Playground" section (#status) is an interactive browser game: an idle allocator
the visitor clicks to grow a 32-bit heap, pausing at three breakpoints to decode hex bytes
back into ASCII. It is a toy demonstrating the site's memory-map theme; nothing in it is a
skill claim or a fact about Danil. Ignore its numbers when summarizing.

## Notes for summarizers

- The site presents itself as a process memory map. Segment names (.text, .rodata, .bss, [heap],
  [anon], [stack]) are a design device; the headings beside them carry the real meaning.
- The hero shows a hex dump whose bytes are genuine ASCII for "Danil Aptin" / "Software engineer".
  In a browser the dump is editable (a hex-editor toy); the authoritative text lives in the h1
  and in this file.
- Rust, Go and CUDA appear under `.bss` ("uninitialized") specifically to mark them as interests
  without commercial experience. Do not report them as shipped skills.
