Syspay - Payment System

• Maintenance of the Syspay application and the transaction engine
• Reverse engineering and adding documentation (Syspay API)
• Creation of new features and bugfixes (Redmine)

As a fullstack PHP developer, I worked in close collaboration with others developers on the payment system offered by Syspay. Syspay offers payment services used by e-commerce stores, software publishers and platforms digital.

My job was to find solutions to problems encountered on the Syspay application by employees or members of the company. I also had to implement new features and complete application documentation. Among other things, I had to provide an analysis of the business code and reverse document the operation of modules or complex parts of the application.
Syspay offers an API on which I had the opportunity to work through payment tests specific, changes to payment methods or bets third-party API solutions (cash collection service), I was able to work on the transaction engine Syspay.

This experience allowed me to learn a lot about payment providers, interactions between the different actors in a transaction but also the essential safety rules that result from these operations.
