Developer Wanted - Erc721 upgradeable contract cleanup and optimization + Testing

Hello,

I am looking for a developer experienced in ERC 721 and Upgradeable contracts. Please view the code In this post

I have a few custom lazy minting functions in there which need to be cleaned up as they are quite expensive to call on mainnet (>$300, currently). In addition, it would be helpful to find and address any security risks. Ideally you will have also worked with implementing royalties w/ EIP 2981, although that may be asking for a bit much!

Compensation can be discussed in private, but ideally I'd like to work with you live on a call to understand what you're doing, and why you're doing it. Final satisfactory completion payment seems like the best route to me.

Thanks!
