Solana Blockchain Developer Needed for Tool Fix

I have a tool designed to reclaim rent fees by closing SPL token accounts. The tool works fine for up to 3 accounts but fails for more.

Key Issues:
- The tool's failure is due to RPC limits, transaction size issues, and account scanning inefficiencies.

Error Messages and Logs:
- There are error messages being generated when the tool fails. I can provide these for troubleshooting.

Required Skills and Experience:
- A strong background in blockchain development, particularly with the Solana network.
- Experience with SPL token accounts.
- Problem-solving skills to suggest strategies to overcome RPC limits.
- Ability to optimize the tool for larger account scanning.

Please note, I currently do not have specific strategies to overcome the RPC limits and would greatly appreciate your suggestions.
