Backend PHP Wordpress / Woocommerce. Implementation of online marketplace payments

I will ask you to implement mobile payments (Przelewy24 or DotPay, or PayU - marketplace solutions prepared by operators) in a marketplace based on WooCommerce, based on the instructions prepared by software developers (several types of payments are already implemented)

The full documentation of the solution on which we base is available here (before submitting the offer, please read it):

Due to the fact that we constantly need minor improvements and certain new functions, I will undertake permanent cooperation with a person / company that will be able to perform smaller / larger jobs on a regular basis.

I care about a concrete, creative and above all experienced person who is not groping and is able to carry out the task conscientiously and reliably. Most willingly, one that is based on WP on a daily basis.
