Project: Healthcare Management System

• Technologies: Java 8, Spring Boot, Microservices, Hibernate, MySQL, REST APIs

Description:

• Developed and maintained a Healthcare Management System divided into three core modules: Patient Records Management, Appointment Scheduling, and Billing System. Each module is deployed as an independent microservice to ensure scalability, fault isolation, and easy updates, while ensuring compliance with healthcare regulations.

Modules:

Patient Records Management:

• Designed and implemented a microservice to manage patient information, including personal details, medical history, and prescriptions.
• Developed RESTful APIs for seamless integration with other modules and external systems.
• Integrated Spring Security for user authentication and authorization to maintain data privacy and security.
• Deployed the service independently, allowing for isolated updates and scaling.

Appointment Scheduling:

• Developed an independent service to handle appointment bookings, reschedules, and cancellations.
• Integrated with the Patient Records service to sync appointments based on patient and doctor availability.
• Ensured data consistency across services using transactional management.
• Deployed as a standalone microservice for independent scalability and fault tolerance.

Billing System:

• Built a microservice to manage patient billing, including payment processing and insurance claims handling.
• Developed APIs for real-time interaction with Patient Records and Appointment Scheduling services.
• Optimized database interactions with Hibernate to ensure high performance in billing operations.
• Deployed independently for isolated updates and high availability.
• Responsibilities:
• Designed and developed microservices for each module, ensuring they could be independently deployed, scaled, and maintained.
• Collaborated with cross-functional teams to enhance system functionality and address issues across multiple services.

• As an Angular Developer, I played a key role in implementing modular and scalable product features, focusing on efficient UI development and seamless data flow. My contributions included:
• Developing reusable UI components using Angular, TypeScript, and RxJS
• Integrating RESTful APIs with Angular services for efficient data retrieval and manipulation
• Handling parent-child component communication using @Input(), @Output(), EventEmitter, and shared services for cross-component state management
• State management using observables and RxJS to handle asynchronous operations efficiently

Project: OneProgram (Entity)

• OneProgram is a web application designed to help management efficiently handle customers, accounts, programs, projects, cost codes, and SOW numbers, each with its own approval workflow. The application is primarily used by senior executives such as CXOs, COOs, and Directors to streamline business operations.

Responsibilities:

• Requirement Analysis – Understanding business needs, defining technical requirements, and designing system workflows.
• Development – Implementing backend logic using Java, Spring Boot, Hibernate, and exposing RESTful APIs.
• Testing – Conducting unit testing, debugging, and ensuring application stability.
• Deployment – Deploying the application on Apache Tomcat 7, configuring environment variables, and ensuring smooth release cycles.
• Post-Deployment Support – Monitoring logs, troubleshooting issues, and optimizing system performance.
• Tech Stack: Java, Spring Boot, Hibernate, RESTful APIs, JSP, Tomcat 7, MSSQL.
• This experience strengthened my expertise in enterprise application development, backend architecture, workflow automation, and deployment strategies.
