"GiroSolution GmbH is a German payment service provider who maintains plugins for a variety of shop systems, for its customers'' use. In the case of Magento 2, we asked Max Pronko to implement the plugin for us. He is a highly professional and very forthcoming person, who implemented the project within the agreed timeframe and was always available for questions and clarifications, even in direct calls via Skype. We appreciate his Magento expertise and will continue working with him, as similar projects come along."
