• Developed a sync job to transfer data from the old application to the new one.
• Learned automation testing as per client request for our project.
• Worked on Disaster recovery activity on Google Cloud Platform (GCP).
• Followed TDD using JUnit and Mockito framework for developing the microservices. Involved in code reviews and training.
• Migrated the Drools version from 5.1 to 7.xx in the Simba application and was involved in migrating Log4j to Floggers.
• Delivered the highest quality software by creating a unit test plan and testing the code thoroughly.

Project: City Union Bank

I worked with BOA, CUB, and UPI Payments. Our database was Oracle, and we used the Spring framework. After scanning a QR code, we determine whether the UPI is affiliated with another bank (offus). If it is, we forward the matter immediately to the NPCI for resolution. If it is on us, we publish the transaction to CBS (core banking s/m) and perform the validations.

Responsibilities:

• Creates various kinds of users and manages the life cycles of the user.
• Participated in the entire application lifecycle of users, focusing on coding and debugging.
• Built reusable code and libraries for future use.
• Collaborated with front-end developers to integrate user-facing elements with server-side logic.
• Worked on troubleshooting and debugging applications.
• Conducted thorough code reviews to identify potential areas for improvement, ultimately enhancing code quality across all projects handled by the team.
• Implemented effective debugging strategies, resulting in fewer software defects and increased reliability.
• Consistently met project deadlines by effectively managing time and prioritizing tasks according to importance.
