Photo Frame

在这个项目中，我操作的是硬件平台选择和自定义视频驱动程序，用于2D加速和透明渲染. 并在嵌入式系统上实现了UI/UX. The work resulted in great UI/UX, 仅使用200MHz CPU, 64Mb DDR和4Mb闪存的成本很好, CI/CD pipeline, 以及自定义呈现框架的测试.

Router Development

开发特定路由器模型的所有技术方面. 这个过程包括使用OpenWRT的一些组件定制操作系统, DD-WRT, and Yocto. 设计了一个自定义的Lua Moonscript框架，带有类似node的调度器.但是在受限的内存环境中运行Lua. 我花了很多精力在前端使用事件驱动的API接收路由器状态更新.

Digital Photo Frame

这个项目是关于一个简单的数码相框, 我在高度受限的硬件上实现UI/UX. Developed a custom font, image, and pixel rendering engine to create a smooth UI with all font dithering; this step gave the product an advantage on the market. As a result, 成本和质量都非常好, 这款产品畅销了好几年.
