Worked on the activemerchant/active_merchant repository to enhance payment gateway integrations by standardizing API version management and improving recurring billing reliability. Introduced a centralized mechanism for fetching and applying API versions across gateways such as Quickbooks, SumUp, XPay, CyberSourceRest, Datatrans, and FlexCharge, reducing integration drift and simplifying future updates. Addressed recurring transaction accuracy by implementing a helper for correct date formatting in the Cecabank gateway. Leveraged Ruby, JSON, and Ruby on Rails to refactor gateway endpoints, expand automated tests, and ensure consistent API usage. The work focused on robust API integration, payment processing, and maintainable gateway development practices.
