Fix Bugs in RWA (Real-World Assets)

I need a frontend Web3 developer to fix bugs in my RWA (Real-World Assets) dApp. The issues are primarily with the menu bar (navigation, responsiveness, broken links) and Web3 integrations (wallet connection, network switching, contract interactions).

Specific problems:

Menu bar:
- Doesn't collapse properly on mobile.
- Active page highlight is incorrect.
- Some dropdown items don’t register clicks.

Web3 integration bugs:
- Wallet Connect / MetaMask sometimes fails to connect on first click.
- After network switch, the menu bar disappears until refresh.
- Balance display (RWA token) doesn't update unless page reloads.
- "Disconnect wallet" doesn't fully reset the UI (menu remains in "connected" state).

Requirements:
- Strong experience debugging React + Web3 frontends.
- Able to reproduce issues locally and provide clean, tested fixes.
- Bonus if you've worked on RWA or DeFi dashboards before.
