Solidity developer to help create 2 contracts optimized for gas and security.

I am looking for a solidity developer that can help me finish a small project. The contracts should be simple solidity code and the job should be short duration. Will compensate well for a short term project. I am looking for an experienced solidity developer with smart contract expertise and a knowledge of the DeFi space.

Deliverables
-create two solidity smart contracts; optimized for gas and security
-clearly explain how the contract works in writing
