Developed custom API integrations for different tenant requirements, ensuring flexible data presentation and secure access to backend remittance functionalities.
Handled error responses and edge cases in API communication, implementing graceful error-handling mechanisms for better user experience during issues like network or server downtime.
Optimized the rendering of EJS templates by implementing caching and minimizing server requests, improving interface load times across tenants.
Utilized Node.js asynchronous programming techniques to reduce response time, especially for data-heavy API calls, ensuring a smooth experience for end-users.
Built features that allow tenant-specific customizations, including custom themes, payment configurations, and localized language options.
Enabled each tenant to configure unique transaction limits, currency options, and remittance destinations through interface adjustments.
Implemented role-based access controls and permissions within the interfaces, allowing tenants to define user roles and secure sensitive data appropriately.
