The application uses PingFederate SSO system, Spring Security and Red Hat JBoss Enterprise application server platform. CAM takes client request using REST API and augments it with additional processable information. AES encryption/decryption techniques are utilized for request/response to Impala 2 system. For system stability, it employs rate limiting techniques to manage incoming requests.
Role and Responsibilities
1. Developed REST API for unique user creation, supporting scenarios with and without additional permissions
2. Inducted role-based restrictions for study level users & Pfizer users (without system level permissions)
3. Created REST service for disabling users, fetching user details like User Id, User roles (study, system, site)

Project Title: CLE (Client: CVS Health Corporation - Aetna HealthCare)
Automated Claim Adjudication System (ACAS) is a mainframe application used for processing health insurance claims including dental, hospital, and medical claims. The system utilizes COBOL for backend processing, DB2 as the database, and CICS (Customer Information Control System) for the frontend interface. ACAS integrates with various upstream and downstream applications to ensure seamless operations. Claim Line Expansion (CLE) a subproject under ACAS, was initiated to enhance the system's capabilities. CLE extended the ability to process expense/service lines from 18 to 99 and increased the override capacity from 45 to 999. Additionally, it expanded the amount processing capacity from one billion to 100 billion.
Role and Responsibilities
1. Revamped the user experience by redesigning CICS screens across various modules, including CLI, CQC, HC, CP, DC, PF 20, EXT-CLI, HI and AS leveraging SDF2 utility
2. Worked extensively towards the CLI/CQC/AS screen modernization: -
a) Enhanced existing search functionality in CLI & CQC screen by identifying recurring pattern
b) Introduced new scrolling and pagination logic for the CLI, CQC, PF 20, EXT-CLI, AS, PD screens
3. Facilitated communication between different applications by integrating IBM/WebSphere MQ

Project
E-Commerce Website

Developed a full-stack e-commerce web application, building both the frontend and backend to create a complete online shopping experience. For the frontend, I utilized Angular, along with TypeScript, Bootstrap, and CSS, to design a dynamic and responsive user interface. This included implementing core functionalities like a shopping cart, secure login/logout features, and access control to protect sensitive user data. A strong emphasis was placed on security, which led me to integrate Okta for secure user authentication and authorization. I implemented the Okta Sign-In Widget for a seamless login/logout process and leveraged the Okta Authorization Server with Java Spring Boot to develop secure REST API endpoints. I ensured robust security by implementing industry-standard protocols such as JWT, OAuth2, OpenID Connect, and SSL/TLS to protect user data and transactions. The backend, which I constructed using Java Spring Boot, provided a scalable and secure RESTful API. I used Spring Data JPA repositories and Spring Data REST to streamline data management and Lombok to reduce boilerplate code. I also implemented features like dynamic product search by category, pagination, and secure HTTPS communication to enhance the user experience and application performance. Secure credit card processing was integrated via the Stripe API, including automated email receipts, with data stored in a MySQL database. Throughout the development process, I utilized modern tools such as IntelliJ, VS Code, Postman, Maven, and npm to ensure efficient code development, testing, and deployment.
