About

Hi, I’m Hyunji Choi, a SAP ABAP Developer with 2+ years in ERP system development, Fiori/UI5, and process integration, complemented by 5+ years of full-stack web development using Java, JavaScript, Spring Boot, React, and Vue. I have contributed to large-scale projects for Kakao, Lotte Card, Korean Air, and Shinsegae. I champion reusable UI components and documented them with Storybook to standardize design and streamline collaboration across multiple documents.

During an internship at Hana Financial TI, I developed a tool to centralize IT security regulations, improving compliance and reducing redundancies. I’ve completed the SAP SYNC Academy to deepen ABAP and Fiori skills, ERP process design, and module integration. I’m eager to apply these capabilities to deliver scalable, integrated enterprise solutions for your team.
