During my time at TargetMedia I worked on the back-end of TargetPay and related systems. TargetPay is a payment service provider, making sure that payments are processed smoothly between the merchant and his or her clients.
The focus of the product is to maximise automation, make the product simple to use, in order to connect many smaller clients. To this end multiple tools are offered, from copy/paste payment screen plugins using JS, to e-commerce plugins, to low-level APIs.
The code base is written in PHP and automated tests are an important aspect of these systems. Ensuring correctness of every written line of code has been my personal objective within this project.
