MuOnline Server Development

I need an experienced developer for long-term work on the MuOnline game server. We will provide full access to the source code for both server and client.

The initial focus will be on:

- User interface enhancements, specifically new menus and navigation

Ideal skills and experience:
- Strong proficiency in C/C++
- Experience in code optimization
- Familiarity with game development, especially in a client-server architecture
- OpenGL knowledge is a plus but not required

The work will be based on deliverables. Please have a look at the code references provided before bidding:
- Client:
