Simple Solana-Web3 App | Looking for a talent with Solana, React and Phantom

I am looking for a talented solana developer with skills of react, solana-web3 and phantom.
I've attached my react app and you can use that.

I want to make this app like following steps:
- There are two wallet addresses in phantom.
- Run this app
- Click "Select" button and connect first address to app
- Disconnect
- Change wallet address in phantom from first one to second
- Click "Select" button and connect second address to app
- Change wallet address from second one to first
Then app is reloaded and string of address need to be changed into first one.
Also, after I connect to first address and change into second one, the app would be reloaded and the address would be changed.

I want to make an app, which is reloaded and change wallet address by changing address in phantom.
