Uni code low level swap

Low level interaction with univ2-like pairs needed. Please apply if have such experience I need solidity developer. Developer has to know solidity assembler and know how uniswap exchange version 2 functioning at low level The job will be in rewriting swap functions in the custom router, so the swap functions can communicate with the uniswap pairs directly. This has to lead to the results such as swapping deflationary tokens without deflationary part.
