- We transformed a legacy mainframe project, the PUP project, into a modern and dynamic Web Application. This existing system, transitioning from a mainframe architecture to a contemporary web-based platform.
- Key Contributions and Achievements:
Technology Migration: Engineered the migration of the PUP project from a legacy mainframe system to a robust and scalable Web Application. The entire functionality was reimagined and implemented using Spring Boot and Spring JPA, ensuring a seamless transition and improved performance.
RESTful API Development: Designed and developed RESTful APIs tailored to the diverse modules of the project. These APIs were meticulously crafted to meet specific requirements, enhancing the project's flexibility and interoperability.
Mainframe Integration: Configured the existing Mainframe VSAM as the database source, pulling data through CICS transaction gateway. This integration facilitated a smooth flow of information between the legacy and modern components of the system.
User Interface Design: Developed intuitive and responsive user interfaces using Angular, HTML5, CSS3, and Bootstrap 4.5. These UI pages were optimized for user experience, ensuring seamless navigation and interaction.
Data Transformation: Implemented XML binding using Maven dependencies, converting Mainframe responses from XML to objects, and further transforming these objects into JSON format. This streamlined data processing and facilitated efficient communication between system components.
Test-Driven Development: Adopted a rigorous test-driven development (TDD) approach throughout the project. Implemented all components, including RESTful APIs and microservices, following TDD methodologies using JUnit. This approach ensured the reliability and stability of the application under various scenarios.
Microservices Architecture: Designed and developed microservices using Spring Boot, adhering to domain-driven design principles. This modular architecture enhanced system scalability, allowing seamless integration and deployment of individual components.
