Hey, I am seeking an individual who can build me an algorithm thatn searches through the blockchain, by following the criteria below. (Solana Blockchain only)

Here's what I need for the algorithm to do:

1. Take out every coin that launched in the past 30 days and reached at least 1M marketcap in solana blockchain.

2. Go to top 100 traders tab (on each coin) on dexscreener.com and take out every wallet from that list.

3. After taking out every wallet (should be around 20,000+ wallets in total), the algorithm must specify which wallet has shown up on multiple of those coins & in how many of those coins.

4. After picking those wallets that had shown up on multiple coins, the algorithm should check the wallet stats (stats like ROI, WINRATE, PROFIT etc) (you can do it in dexcheck.ai - wallet analyzer tab)

5. Both the wallets and their stats should be uploaded into a google sheet for better manual analysis.
