Advanced Discord Bot

Personal Project • 2024 - 2025

Developed a multi-functional Discord bot using Python (discord.py) with an asynchronous (asyncio) architecture. The bot supports music playback (YouTube, Spotify), advanced administrative commands, and a complex interactive UI system.

  • Implemented an asynchronous music player with queue management (`asyncio.Queue`), supporting `yt-dlp` and `ffmpeg` for audio streaming.
  • Designed a complex visual embed builder ('/constructor') using interactive `ui.Modal` and persistent `ui.View` components for live-preview editing.
  • Built an interactive `/help` command and player control panel using `ui.Select` and `ui.Button` components.

University Schedule Caching

Personal Project • Feb 2025 - Mar 2025

Built a web app to fix the university's slow and unreliable schedule API. The backend service caches API data in Redis and provides a fast, stable endpoint for a simple frontend.

  • Built a Flask backend with Redis and Celery to cache data and manage API requests.
  • Stored schedule data in SQLite with automatic cache invalidation.
  • Secured backend with API key authentication via Nginx and deployed with Docker.
