• YouTube Audio Harvester: Desktop app that bulk-downloads channels and playlists as audio with a 13-worker thread pool, proxy rotation with automatic banning of failing proxies, and retries; auto-categorizes tracks, removes silence with FFmpeg, de-duplicates via SQLite, and reports progress to Telegram. Python, yt-dlp, FFmpeg, CustomTkinter.
• Android Emulator Automation Platform: Manages fleets of LDPlayer/MEmu instances (clone, configure, boot, tear down) with a UI-automation engine that reads the live screen hierarchy instead of fixed coordinates, and a file-locked registry so parallel workers never collide.

• AI Email Outreach App (client project): PyQt5 desktop app that parses the client's CV, writes personalized emails with the OpenAI API, sends on a schedule over SMTP, and tracks replies via IMAP.
• Telegram Tools Suite: Built a set of Telegram desktop apps and bots: a session manager with drag-and-drop import/export, validation, restriction checks, and TData-to-Telethon conversion; a real-time marketplace tracker with instant alerts; a multi-threaded group discovery tool that classifies groups by topic, language, and region using pluggable AI providers (Gemini, Groq, Kimi, Ollama); and a link generator that parses price updates in any language with the Claude API. Python, Telethon, Pyrogram, aiogram, PyQt5, SQLite.
• Desktop tools for clients: Multi-method website email scraper with Excel export (BeautifulSoup) and a scheduled bulk email sender with attachments (SMTP, PyQt5).
