Developed and delivered a Mercado Pago Payment Plugin for the davila7/claude-code-templates repository, enabling seamless payment integration for marketplaces operating across multiple countries and supporting diverse products. The work focused on building a robust plugin architecture that streamlines cross-border checkout flows and reduces integration complexity for sellers. Leveraging skills in API integration, payment processing, and plugin development, the implementation utilized JSON for configuration and data exchange. This feature expanded the marketplace’s capabilities by supporting additional payment options, accelerating time-to-market for new sellers, and enhancing potential revenue streams without introducing major bugs during the development period.
