During June 2025, Seolhee Choi developed a comprehensive sales creation and registration workflow for the seolhee-choi/B2B-Demo repository, focusing on improving efficiency and accuracy in order management. Leveraging Vue.js and JavaScript, Seolhee built a dedicated page with a form for capturing customer and product details, pricing, delivery, and shipping information. The implementation included integrated product search by code, real-time calculation of final sale amounts after discounts, and robust input validation to ensure data integrity. By introducing reusable UI components and modals for customer and product search, Seolhee established a scalable foundation for future enhancements in frontend development workflows.
