Yunhan combines software engineering experience with an interest in developer cognition, UX research, developer experience, and coding agents. At Mocha Software Co. Ltd., Yunhan developed a conference system for China Mobile Migu Culture & Technology Group using Spring, Spring MVC, and MyBatis. Yunhan used Git, GitLab, and Maven in the program’s development and management processes applied Ajax to reduce web-page rendering time from 1 second to 0.5 seconds and improved system efficiency by reducing administrator logging speed to 0.1 seconds. Yunhan also used dynamic SQL in place of traditional SQL searches to reduce search-engine workload and used Redis to store single sign-on user dialogue. Yunhan’s design philosophy focuses on guiding users’ thinking and understanding rather than only automating tasks, with the aim of producing sustainable, maintainable outcomes. Yunhan has hands-on UX research experience spanning study design, participant recruitment, and analysis of brain signals and interaction patterns for developer tools. ## Services - SQL - Model-View-Controller \(MVC\) - Git - MyBatis - Spring MVC - Dynamic SQL - JavaScript - Java - Spring Framework - Python \(Programming Language\) - Maven - Single Sign-On \(SSO\) - Artificial Intelligence \(AI\) ## Highlights - Developed a conference system for China Mobile Migu Culture & Technology Group at Mocha Software Co.
