Smart contract Gas Fee issue

Hello,

i have been working for the past month on a smart contract with really interesting and advanced features like Arbitrage Pair Management, Flash Loan Integration, DEX Swaps and Profit Calculation, MEV and Flashbots Protection, Gas Control and Optimization etc.

the contract compile and deploy without problem, but since the last few adjustments now i have fees in the 3.000$ range to deploy the contract, i am setting up a batch script to merge multiple operation in one to keep the gas fees at minimum, but, for the love of God, i can't reduce the fees like they used to be, minimum range now is 900$ per deployment.

i want to specify i am testing on sepolia and through local hardhat network until the contract will be finished.

Anyone can help eventually with some tips that can improve the gas fee management?
