Industrial Printing Equipment — Product Catalog & Quotation Platform. 1 Year 4 Months

• Developed a product catalog and quotation-based web application (not an ERP system) for an industrial printing equipment business using Java, Spring Boot, and Hibernate, enabling customers to browse products, request quotations, and track service tickets.
• Built a Quotation Request feature so customers could directly inquire about products with variable, non-fixed pricing — in place of a checkout/payment flow, since payment integration was not required for this use case.
• Implemented JWT-based authentication and role-based access control using Spring Security for admins, engineers, and customers.
• Designed RESTful APIs for product management, service tickets, engineer allocation, and invoice generation with proper HTTP status handling.
• Built Inventory & Image Upload backend module with AWS S3 integration for storing engineer service reports and QR code images.
• Developed an Angular-based Admin Dashboard with TypeScript, reactive forms, and routing for real-time reports and quotation tracking.
• Containerized services with Docker and docker-compose; configured a Jenkins CI/CD pipeline for automated build, test, and deployment. Used Claude (AI coding assistant) for rapid prototyping of REST endpoints and Angular components, reducing development time on new features.
• Optimized SQL queries and implemented pagination in Spring Data JPA repositories, improving overall API performance.
