Systems, backend and reverse engineering. Rust and Python services, teardown of closed protocols and undocumented APIs, C/C++ firmware for ESP32, and the Linux boxes underneath. MSU student.
Systems and Rust. Async services on Tokio, CLI tooling, and native Rust cores
behind Flutter interfaces through flutter_rust_bridge. Memory is handled by hand,
not by a garbage collector.
Backend and Python. AsyncIO services on FastAPI, Quart and Flask, SQLAlchemy for storage, httpx and aiohttp for clients, curl_cffi where the request has to pass as a real browser.
Reverse engineering. Proprietary wire protocols, undocumented APIs and unofficial SDKs. Traffic analysis in Wireshark and Fiddler, and requests that have to get past Cloudflare and anti-bot checks.
Embedded. ESP32 and ESP8266 firmware in C/C++ on FreeRTOS: sensors, servos, a task scheduler of my own, and a shell that runs on a microcontroller.
Telegram. Bots and userbots on Aiogram 3, Pyrogram and Telethon, with payments, subscriptions and admin panels.
Linux. Ubuntu, Debian and Arch; systemd, nginx, Docker, PostgreSQL, SQLite, Redis.
