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 PHP full-stack developer at Syspay, I worked closely with the development team on a payment platform used by e-commerce businesses, software providers and digital platforms.

My role involved maintaining and evolving the application, investigating and resolving issues reported by internal teams, developing new features and improving technical documentation. I also worked on analyzing business logic and reverse-documenting complex modules to make them easier to understand and maintain.

I worked extensively with the Syspay API and transaction engine, including testing specific payment scenarios, evolving payment methods and integrating third-party services related to payment processing.

This experience gave me a strong understanding of the online payment ecosystem, the interactions between the different parties involved in a transaction, and the reliability and security requirements associated with payment systems.
