Developed Scripted REST APIs and self-rearming background jobs in ServiceNow to process article batches within transaction limits, improving reliability and resolving issues such as weighted-scoring defects and Run ID race conditions. Built an AI-assisted evaluation and review application using ServiceNow AI Agent Studio and Now Assist, enabling field-level scoring and automated reviewer-approved revisions via UI Builder. Reduced AI processing consumption by prototyping a Virtual Agent review flow that significantly lowered Now Assist usage. Owned feature requirements across user stories, acceptance criteria, workflow behavior, and testing scenarios within Agile sprints, and supported end-to-end workflow delivery by collaborating with testing and refining agent behavior based on review results.

Developed backend services for patient registration and visit scheduling using Java, Spring Boot, REST APIs, SQL, and Spring Data JPA to support healthcare workflows. Improved API efficiency by introducing DTO-based contracts to decouple persistence models from frontend responses and return only required data. Strengthened security using Spring Security and stateless JWT authentication with request validation and structured error handling. Reduced integration testing defects by adding JUnit tests and aligning React/TypeScript interfaces with backend DTO contracts. Built frontend-backend API integrations and supported end-to-end testing of registration and scheduling user flows, including validation and error scenarios.

Implemented portfolio and transaction management features using Spring Boot REST APIs and Angular interfaces within a financial portfolio management application. Used Hibernate/JPA with MySQL for persistence and validated APIs using Postman. Supported build and deployment workflows with Git, Docker, and Maven and assisted with AWS CI/CD deployment workflows using Amazon ECR and EKS. Performed end-to-end testing of REST endpoints, database operations, and frontend workflows across portfolio and transaction modules.
