Profile

Rust developer with hands-on experience through independent and academic projects in asynchronous backends,
cross-platform process management, real-time networking, and native audio integration. Builds software across the
stack: Rust services, browser and native interfaces, scripting integrations, and GitLab CI/CD release workflows.
Cybersecurity master’s student and third-place finisher at the All-Ukraine Cyberhackathon 2025. Interested in Rust
backend, systems programming, and security-focused engineering roles.

Technical Skills

Core: Rust, Tokio, Axum, reqwest, Serde; Python, FastAPI; C/C++ interoperability and FFI.
Networking & data: REST APIs, WebSockets, QUIC/Quinn, TCP/TLS, SQLite (rusqlite, SQLx), MongoDB;
OAuth 2.0/PKCE integration.
Systems: Linux and Windows APIs, process lifecycle management, PTY/ConPTY, cgroups v2, Windows Job
Objects, CPU affinity; Rust cross-compilation for x86, ARMv7 and AArch64.
Audio & extensibility: miniaudio, Opus, SpeexDSP, RNNoise-based processing; Lua/mlua, WebAssembly/wasm-
bindgen.
Interfaces: JavaScript/HTML/CSS, Svelte 5/SvelteKit, Vue 3; egui/eframe, GPUI; Servo embedding prototypes.
Delivery & testing: Git, GitLab CI/CD, Docker, shell/Python automation, Cloudflare Workers/R2; Rust
unit/integration tests, pytest.

Selected Engineering Projects

K.E.Y.S.T.O.N.E. - Distributed Process Management 2026
Independent project | Rust, Axum, Tokio, Svelte 5, SQLite, Lua

• Built a panel-and-daemon architecture for managing application and game-server processes across multiple hosts,
with REST APIs, instance persistence, restart policies, and remote file operations.
• Implemented interactive browser terminals relayed over WebSockets to pipe/PTY processes, including terminal
resizing and lifecycle events.
• Implemented CPU, memory and affinity controls using Linux cgroups v2 and a Windows Job Objects backend;
documented platform-specific limitations and native validation requirements.
• Added Argon2id password hashing, cookie sessions, CSRF/Origin checks, and per-user grants for remote hosts,
instances, files and presets.
• Built Lua-driven installation presets with execution limits and background jobs; configured Linux/Windows and
ARM-target build workflows.
Conduit - Self-hosted Communication Platform 2024–present
Independent project, in development | Rust, Quinn, C/C++, Opus, Lua

• Developed QUIC voice transport and a separate TCP/TLS command service, with channel routing and SQLite-
backed message/audit storage components.
• Built a C++/C ABI/Rust FFI audio layer over miniaudio for device selection, capture and playback; integrated
Opus and noise-processing components.
• Separated the client backend from UI experiments in Servo, GPUI and Tauri; exposed Lua scripting through a
local daemon bridge and prototyped WASM/canvas controls.
• Created multi-stage GitLab pipelines for component builds, packaging, version metadata, R2 release distribution
and a GUI updater.
Minecraft Authentication Service 2026
Independent project | Rust, Axum, SQLx/SQLite, Svelte 5

• Implemented Yggdrasil/authlib-injector-compatible authentication endpoints, account roles, invitations, token
lifecycle operations and administrative password reset flows.
• Added image-upload validation, hash-based texture storage, signed texture metadata and a browser account-
management interface; provided Docker packaging and smoke-test scripts.

Additional Selected Projects

GPUI Compatibility Patch 2026
gitlab.com/BassetMC/adabraka-gpui-patch

• Patched an existing GPUI distribution for Linux/X11 compilation, Rust/WGSL buffer-layout alignment and
Linux-to-Windows cross-compilation; adjusted shader-build fallback and resource integration without changing
the public API.
Auto Changelog - Local LLM Developer Tool 2026
gitlab.com/BassetMC/auto_changelog
• Built a Rust CLI that analyzes changed lines from Git history and generates Ukrainian changelog entries through
local llama.cpp inference, with Vulkan GPU-layer offload, model download options and non-interactive operation.
MCBuilder - Minecraft Modpack Builder 2026
gitlab.com/s.d.l-minecraft/minecraft-modpack-builder

• Built a Rust/Axum backend and Vue 3 interface integrating the Modrinth API, recursive dependency resolution,
client/server mod selection, bounded concurrent downloads and build-progress reporting.
Other hands-on work:
• Python media workflow: FastAPI, SQLAlchemy and Google OAuth/PKCE integration with background
FFmpeg processing and YouTube API upload workflows.
• Android Rust application: egui/eframe native activity, SQLite-backed dictionary data, text-to-speech integra-
tion and audio playback.
• Reusable Rust tools: asynchronous streaming downloader with bounded concurrency and progress reporting;
Windows named-pipe IPC with Python; C FFI file-timestamp utility; experimental parser/interpreter with
host-function bindings.

Internship & Academic Experience

Cyber Police of Ukraine - Internship 2022–2023
Ternopil, Ukraine
• Developed Python/Rust automation tooling, including application components, a package manager and update
delivery, to simplify software setup and distribution for other interns.
Virtual Laboratory - Department of Physics Collaboration 2021–2024
Ivan Puluj Ternopil National Technical University

• Contributed virtual-environment interactions and logic to an educational simulation project; developed Rust/Rocket
backend components using SQLite.
• Project publication: TNTU institutional repository.
