Responsibilities:

● Developed the functionalities using Agile Methodology and involved in Agile scrum processes such as daily stand-up meetings, sprint planning, sprint demos, etc. Agile/ Scrum methodology to track project progress and participate in Scrum meetings.

● We work closely with Business Analysts and use the Rally tool to understand new requirements step by step. Initially, we analyze the new features based on our experience, followed by a story huddle with the Business Analyst for clarification and alignment. After that, we proceed with implementation using Spring boot and conduct an internal development code review.Once development is complete, the ticket moves to peer code review. Our peers review the code against coding standards and provide feedback in the task section if there are any suggestions or issues. We address the comments and resubmit the code for another round of review. Once everything is approved, we provide a demo of the feature to the Business Analyst.

● Developed and maintained Kafka-based event-driven architecture to enable efficient data exchange between distributed services.

● Interact with business people and get requirements from them and build the application accordingly and work on bug fixing also.

● We use the Lightrun tool to debug applications in the production environment. Since production applications are deployed on external servers and run on different ports, direct debugging is not feasible. To identify and resolve issues, we utilize Lightrun to set dynamic logs or breakpoints at specific code locations. This allows us to capture real-time data and diagnose bugs without interrupting the application's normal operation.

● We use the Splunk tool to identify the root cause of errors in the Echo, PROD, Alpha, Bravo application and provide appropriate solutions based on the findings.

● Using Dbeaver, Production Development Update Tool (PDUT) for writing SQL queries for Update, Select in query on a day-to-day basis.

● DBeaver and the PDUT tool work in conjunction for database operations. Direct execution of update queries is not permitted. Instead, we draft the query in DBeaver and then submit it through the PDUT tool. After managerial approval is granted within PDUT, we proceed with executing the query.
