Projects

OBVAM Implementation - SMBC Bank

July 1, 2025 – Present

Delivered SMBC-specific customizations for Oracle Banking Virtual Account Management by extending product screens and Java backend services across collections, virtual account setup, secure APIs, statements, and reporting workflows. Built and enhanced REST APIs, CRUD services, and Oracle DB persistence modules for virtual account data using Java 8/11, Spring Boot, JPA/Hibernate, and reusable design-pattern-based components to improve maintainability and release consistency. Supported integration of 4+ enterprise systems, including OBVAM, T24, OBPM, OBRH, and digital channels, enabling secure end-to-end virtual account processing and routing across banking platforms. Implemented OAuth 2.0 and JWT-based authentication for inter-system communication and helped improve API security, access control, and production-readiness for banking integrations. Handled 3+ operational modules, including PLATO jobs, batch processing, statement generation, and end-of-day support, helping ensure smooth execution of business-critical banking activities. Participated in deployment, container management, and Docker-based release support in enterprise environments aligned to Kubernetes-oriented DevOps practices, improving deployment traceability and operational stability. Resolved SIT, UAT, and production issues through debugging, root cause analysis, and exception handling, contributing to faster defect closure and more stable service delivery across testing and release cycles. Worked on concurrent issue analysis and multithreading-aware backend debugging for batch and API flows, helping improve reliability during peak operational and end-of-day processing windows.

Card Management System - Canara Bank Head Office, Bangalore

May 1, 2021 – June 1, 2025

Developed Spring Boot REST APIs and backend modules for 6+ card lifecycle operations, including issuance, activation, blocking, PIN management, transaction processing, and status management in a large-scale banking application. Designed and implemented microservices-based services using modular and design-pattern-driven approaches, improving service isolation, maintainability, and supportability for card management workflows. Implemented Spring Security with OAuth 2.0 and JWT for secure authentication and authorization of card-related APIs, strengthening API protection for internal and integrated banking services. Designed and managed Oracle SQL schemas for cardholder data, transaction history, audit records, and workflow processing, while supporting PostgreSQL and MySQL for application data handling and query tuning. Optimized SQL queries and indexing strategies that reduced application load time by 30% and improved backend response efficiency for transaction-oriented services. Implemented Spring Batch jobs for bulk card generation, scheduled updates, and batch execution, supporting high-volume backend processing in production banking environments. Performed code fixes, unit testing, integration testing, and root cause analysis across API, batch, and database layers, helping improve release quality and reduce recurring production defects. Supported deployments, application monitoring, and production incidents across multiple backend modules, improving turnaround time for debugging, exception handling, and operational issue resolution. Worked on concurrency-sensitive transaction flows and multithreading-related debugging in service and batch execution paths, improving stability of card processing operations during business-critical runs.
