Make a review of the code and remove unnecessary functionality (back-end in php)

Hello.
There is a ready-made code for the marketplace with an unlimited number of suppliers, we do not need many of the features prescribed in it at this stage.

Therefore, I am looking for a person who will make a review of the code, throw out the excess, finish a few important integrations and get along with the front. (also if it can support after launch - it will be generally cool)

It is also important to be prepared for stupid questions on my part and conduct a short educational program in the process of dialogue and work)

Link to the project - https://github.com/aimeos/aimeos

Experience in e-commerce and working with marketplaces will be a big plus

In response, throw cases
