Sanda University
Developing HarmonyOS applications and contributing to open source alongside undergraduate study.
About me
I am Jianghao Yu, an undergraduate in Computer Science and Technology at Sanda University. I build HarmonyOS mobile and PC applications, work on full-stack products, and contribute to OpenHarmony adaptation. As of October 2026, I have released 139 applications across mobile and PC, based on my own records. My work connects product development, open-source contribution and technical knowledge sharing.

Education
Experience
Shanghai Electric Group Traffic Automation Systems Co., Ltd.
Contributed to full-stack implementation of a departmental platform and related business subsystems.
Independent HarmonyOS development
139 applications released across mobile and PC, based on my own records. Work spans requirements, ArkTS/ArkUI development, adaptation, testing and release iteration for utility, education and productivity apps.
Selected projects
CheckMe
Built device information, hardware monitoring, snapshot history and comparison with ArkTS/ArkUI and native C++/N-API integration. Adapted the PC version for 2-in-1 windows and Canvas resizing. Foreground sampling runs about every 2 seconds with 30 CPU trend points; supports 7 widget types and up to 10 snapshots. Background widget refresh follows system scheduling.
OpenHarmony embodied intelligence practice
Created MuJoCo/MJCF simulation scenes including a logistics factory, bedroom and study, integrating robots and furniture. Implemented Python logic for state reading, obstacle avoidance, area cleaning, battery management and occupancy grids. Completed the project; completion certificate dated 5 Feb 2026.
Temporal Persona
Built frontend screens and interactions for a team project involving AI personas, multi-agent conversations and meeting notes. Integrated cross-device sharing with ShareKit and preloaded poster assets in the sandbox to improve sharing preparation.
