Anonymous Vibrant Chat Platform

I'm seeking a developer to create a web-based anonymous chat platform with the following features:

Login/Entry:
- No phone number, email, or password required.
- Users simply choose a nickname to join.

Group Chat:
- Public group chat room upon entry.
- All nicknames and messages visible to everyone.

Private Chat (Mutual Like System):
- Users can "Like" other nicknames.
- If two users "Like" each other, a private chat box opens automatically.

Features:
- Real-time messaging (both group and private).
- Online user list.
- Simple, modern UI with a vibrant, blue and white color scheme (dark mode preferred).

- Moderation feature allowing admin to remove inappropriate content.

Technology Stack (Suggested):
- Backend: Node.js + Express + Socket.IO
- Frontend: HTML, CSS, JavaScript (React is acceptable)
- Database: Not required for basic version (can use in-memory), optional upgrade to Redis/MongoDB for scaling.
- Hosting on free/cheap servers like Render, Railway, or paid VPS.

Ideal Skills and Experience:
- Proficiency in Node.js, Express, and Socket.IO.
- Strong frontend development skills in HTML, CSS, JavaScript, and/or React.
