What I'm looking for

I’m seeking a Java Backend Developer position.

At VNPT-IT, I develop and fix business features for iOffice V6, an electronic document management system. I work on incoming and outgoing document workflows using Spring Boot, Spring Data JPA, and Oracle, handling Jira tickets and addressing feedback from testers and customers.

On iOffice V6, I contribute to a multi-tenant microservices system that manages document processing across organizations. Its workflows cover drafting, review, approval, publication, and document exchange, with permissions based on organizations, roles, groups, and menus.

I also built the backend for Vườn Hoa Tươi, a personal online flower shop project, as a monolith with APIs for accounts, products, carts, orders, and discount codes. I’m seeking a Java Backend Developer position.
