Project: GSP - Global Securities Processing

Client: BNY Mellon

Backend Development:

Working on backend development using Java 17 and Spring Boot 3 to build and maintain scalable microservices.

Frontend Development:

Contributed to UI development using Angular for specific modules.

API Management:

Designed and implemented RESTful APIs to support internal service communication and external integrations, following REST best practices.

Cloud & Deployment (CI/CD Pipeline):

• Deployed microservices using Docker containers via Google App Engine. CI/CD pipeline setup is handled using Jenkins and assembly files.
• Familiar with AWS services such as S3 (actively used for file storage), EC2, IAM, and Lambda for cloud readiness.
• Gained an understanding of Kubernetes for container orchestration and troubleshooting in deployment environments.

Database Management:

• Utilized Oracle DB for backend data storage and GraphQL for efficient querying and data retrieval. Handled schema versioning with Liquibase.
• Also familiar with MongoDB and NoSQL concepts, including unstructured data modeling and document-based access patterns.

Automation and Testing:

Developed JUnit and executed Cucumber, Selenium, and TestNG test cases for automated regression and feature testing.

Version Control & Collaboration: Actively using Git for version control, Jira for task management, and Confluence for documentation and knowledge sharing.

Logging and Monitoring:

• Utilized Splunk for centralized log management, enabling efficient monitoring, alerting, and troubleshooting of application logs.
• Employed SonarQube for continuous code quality analysis, integrating it into the CI/CD pipeline to maintain code standards

Agile Methodology:

• The project follows Agile practices with sprint-based releases, daily stand-ups, sprint planning, and retrospectives.
• Regularly involved in grooming sessions, demo reviews, and backlog refinement.

Collaboration and ownership:

Regularly collaborate with cross-functional teams for requirement analysis, integration testing, production deployment, and resolving bugs or critical issues during UAT, and live support phases.

Project: BT WLMS

Client: British Telecommunications

• Worked as part of the Data Warehouse (DWH) team, responsible for processing and managing data feeds.
• Developed backend logic using Java, SpringBoot and Spring Batch to process scheduled data jobs.
• Designed and maintained stored procedures to handle large datasets and feed processing logic.
• Automated daily feed generation using cron jobs, ensuring timely delivery of output files to external clients.
  Some feeds were configured to interact with Oracle databases, and output files were generated according to the client format.
• Migrated parts of the backend system from Spring to Spring Boot to simplify configuration and deployment.
• Used Apache Kafka for messaging between internal modules, where applicable.
• Prepared low-level design (LLD) documents and participated in discussions with business analysts and other stakeholders to understand data requirements.
• Involved in defect fixing, performance tuning, and ensuring that scheduled jobs ran without failures
