Modular Discord Bot Marketplace Integration

I need a developer who can build a fully modular Discord bot that supports plug-and-play extensions and ties directly into a small marketplace accessible from both a dedicated web panel and inside Discord itself.

The core of the job is to create a solid plugin architecture: each feature must live in its own folder or package, register itself automatically on start-up, and be hot-swappable without taking the whole bot offline. Think of it as a mini “app store” where administrators can enable, disable, buy or download new modules at will.

Marketplace integration is required on two fronts:
• Inside Discord: slash commands or buttons should let authorised staff browse available modules, view descriptions, and install or remove them instantly.
• On the website: a clean dashboard (React, Next.js or similar—your call) should mirror the same catalogue, handle authentication through Discord OAuth2, and push the chosen module to the running bot via a secure API or WebSocket.

Essential pieces I expect at hand-over:
• Core bot framework with plugin loader, error isolation, logging and permission checks.
• Sample modules that prove the system works (e.g. a simple utility command and a fun entertainment mini-game).
• Marketplace front-end + back-end, fully wired to the bot and able to distribute zipped or NPM-style packages.
• Installation guide and clear developer notes so future contributors can write their own plugins.
