Experience

Software Developer

Deloitte

Sept 2025 — Present

—Engineered the migration of a legacy JSP/Servlet monolith to a Spring Boot–based microservices architecture, leveraging
—Led the modernization of a legacy JSP/Servlet-based MVC application into a Spring Boot–driven service-oriented architecture, improving scalability, modularity, and deployment efficiency across the ASPEN platform.
—Refactored tightly coupled presentation logic by decomposing legacy JSP/Servlet flows into Spring MVC controllers and developing React-based interactive UIs, significantly improving user experience and maintainability.
—Designed and implemented RESTful APIs using Spring Boot to support real-time interactions between modern React frontends and backend eligibility and productivity services.
—Contributed to the IMPACTS productivity platform, developing Spring Boot backend services and React-based gamification dashboards to track case worker performance, task completion metrics, and workflow efficiency.
—Integrated Amazon Connect task-based routing to enable asynchronous task processing and intelligent task assignment for case workers, improving workload distribution and reducing manual task handling.
—Worked on Amazon Connect Task Control Panel integrations, enabling backend services to publish, update, and track tasks routed to case workers based on skill sets, availability, and priority.
—Implemented backend workflows to synchronize Amazon Connect task events with internal case management services, ensuring real-time task status updates and seamless user experience for case workers.
—Optimized complex SQL queries and indexing strategies in MySQL/Oracle databases, reducing query latency by approximately 25% and improving performance of eligibility and productivity workflows.
—Implemented JWT-based authentication and Spring Security filters, enforcing secure access control across microservices and protecting sensitive eligibility and task data.
—Developed reusable, high-performance React components using hooks and centralized state management, reducing UI complexity and enabling consistent patterns across ASPEN and IMPACTS applications.
—Built centralized exception handling, logging, and observability mechanisms using Spring AOP, SLF4J, and structured logs to improve production monitoring and troubleshooting.
—Ensured system stability through unit, integration, and API testing using JUnit, Mockito, and Postman, supporting safe feature delivery during continuous modernization efforts.
