   As part of a dynamic team, I contributed to the development of an internal banking application designed to replace the existing vendor tool for collection and recovery services. This ambitious project had a significant impact, with an initial rollout affecting over customer accounts, setting the stage for broader implementation.In this role, I developed an Angular application that interfaces with several existing APIs currently utilized by the vendor tool. This integration involved managing over 70 API endpoints, ensuring seamless communication between the application and backend systems.A critical aspect of the project was migrating these APIs to AWS, which involved transforming 30 legacy APIs written in JAVA and Scala into modern, more efficient versions. This migration process encompassed around 50 APIs, enhancing their performance and scalability.Additionally, I played a key role in incorporating APIs developed in Go, which significantly improved the application\'s functionality and performance. These enhancements supported transaction processing for over 180 branches, ensuring robust and reliable operations across the network.To manage real-time data processing, we utilized Kafka streaming services. This setup handled over transactions daily and processed data from customer interactions per month. This capability was crucial for maintaining the application\'s responsiveness and efficiency.Overall, my contributions to this project demonstrated my skills in application development, API management, and real-time data processing, highlighting my ability to support large-scale banking operations and drive significant improvements in performance and functionality.
