▸Developed and maintained microservices using Java and Spring Boot to power core retail modules including product catalog, pricing and promotions, shopping cart, and order management, supporting high daily traffic. ▸Built responsive frontend screens in React with reusable components, integrating them with backend REST API endpoints for real-time product, inventory availability, and checkout data. ▸Designed and exposed secure RESTful Web Services and applied Spring Security with role-based access control and JWT-based authentication for customer accounts and checkout operations. ▸Implemented data persistence using Spring Data JPA and Hibernate over PostgreSQL, optimizing SQL queries and indexing to reduce response times on high-traffic catalog and order endpoints. ▸Containerized services with Docker and deployed to AWS (EC2, S3), and automated build and release pipelines using Jenkins and Maven for CI/CD. ▸Wrote unit and integration tests with JUnit, participated in code reviews, and collaborated in an Agile/Scrum team using Jira and Bitbucket.

▸Developed backend modules for production tracking, work orders, and inventory management using Java, J2EE, and Spring MVC within a microservices-based architecture. ▸Created and consumed REST API services to connect the React frontend with inventory, materials, and supply-chain services, improving data accuracy and screen load performance. ▸Implemented frontend features using React, JavaScript, HTML5, and CSS3, building dynamic, interactive screens for production and inventory views. ▸Worked with MySQL and MongoDB to store production and material master data, and applied multithreading to handle concurrent order and batch processing efficiently. ▸Used Git for version control and Maven for build management, and supported deployments on Apache Tomcat in lower environments. ▸Resolved production defects, contributed to sprint planning, and improved code quality through JUnit test coverage.
