Wirecard hired me in 2018 as part of their "Shop Systems" team. The responsibility of this team was to maintain the integrations of the Wirecard Payment Gateway in multiple shop systems. During my tenure we integrated many new features such as 3D Secure payments, a fully revamped credit card workflow, an improved i18n workflow, a whitelabeling solution for enterprise customers to resell the payment gateway and a whole range of other things.
The plugins processed more than $100 million in transactions per year and were used by Wirecard's customers all over the world.
Working for Wirecard over 1.5 years allowed me to gather a deeper insight into fintech and ecommerce, as well as working within an enterprise framework of processes.
(My tenure ended in December 2019, shortly before the scandal. I don't know where the missing money is. 😅)
