Worked on the openfintechio/openfintech repository to expand the payments ecosystem by integrating STBL as a new payment provider, supporting both bank transfer and QR code payment methods. Focused on enhancing currency support, the work enabled ARS and BOB transactions across payment flows, broadening regional coverage for merchants. Addressed data integrity by resolving merge conflicts in JSON-based data management files, ensuring stable integration of new providers. Leveraged skills in API integration and payment processing to streamline provider management and deliver business value. The changes allowed live STBL payments, increasing market reach and supporting operational needs for diverse payment scenarios.
