Modern Chat Integration for WordPress Community

I'm seeking an experienced WordPress developer to finalize integration on my social community website. The site uses BuddyPress and Better Messages for member interactions.

Key Tasks:
- Cleanly integrate a common members chat box with a modern visual style.
- Ensure the chat box includes:
- File sharing
- Emojis and GIFs
- Message notifications

Ideal Skills:
- WordPress development expertise
- Experience with BuddyPress and Better Messages
- Strong design skills for modern UI

Everything is set up; I need someone to polish and finalize the integration.
