Developed and unified Alipay payment solutions within the langgenius/dify-plugins repository, focusing on both feature expansion and architectural consolidation. Leveraging Python and plugin development expertise, the work began with the rollout of two distinct plugins: one for Alipay payments and another for Alipay subscriptions, enabling enhanced payment processing and service subscription capabilities. Subsequently, these plugins were consolidated into a single, cohesive solution through careful refactoring, renaming, and branding updates, which reduced fragmentation and streamlined maintenance. This approach aligned the plugin suite with broader product strategy, demonstrating end-to-end capability in payment integration, deployment, and modernization within a one-month development period.
