These APIs were seamlessly integrated with frontend applications, ensuring smooth functionality. Moreover, I successfully integrated third-party payment gateways and billing systems with Spring Boot APIs, enabling effortless subscription payments and recurring billing functionalities.We employed MySQL to handle relational data, which involved complex joins and transactions. Additionally, we utilized Cassandra, a NoSQL database, to store and retrieve unstructured or document-based data like user profiles or log entries. Furthermore, we leveraged the Redis engine to optimize data storage and retrieval for improved performance. Developed and maintained back-end services, APIs, and server-side applications for the library organization project using Node.js. Leveraged Node.js's event-driven architecture and non-blocking I/O model to build scalable and high-performance back-end solutions. Implemented real-time collaboration features using Node.js and Web-socket technology, enabling users to interact and collaborate on library-related tasks in real-time. Employed Kotlin for back-end development, building Restful APIs, micro-services, or server-side components to support OCLC's digital initiatives. Leveraged Kotlin's co-routines and asynchronous programming features to implement efficient concurrency models and asynchronous operations within the OCLC project. Show less

Here comes my specific role, by using this annotation, I created a task that periodically checks for upcoming payments and sends reminders accordingly. In the frontend part, we used Angular.js for creating dynamic and responsive user interfaces. Its data binding capabilities and two-way communication facilitated real-time updates and interactions, delivering a smooth and engaging user experience. We relied on on-premise Tomcat servers to host and deploy our application, ensuring a secure and controlled environment for the financial services. Tomcat's reliability and performance allowed us to manage heavy traffic and serve customer needs efficiently. For data management and storage, we used SQL Microsoft server so that we can handle relational database capabilities, complex data structures and queries, ensuring data integrity and accessibility for critical financial transactions.The project emphasized security and compliance as paramount concerns. We implemented stringent measures to safeguard sensitive customer information and maintain compliance with industry regulations, building trust and confidence among users.Throughout the development cycle, our agile and collaborative approach fostered effective communication with stakeholders, ensuring alignment with business objectives and rapid response to changing requirements.
