At Xiamen Xinyu Xinglian Technology Co., Ltd., I architected and delivered the full-stack foundation for an overseas AI Agent companion platform. I built its dynamic multi-model gateway and layered memory service, and implemented token cost auditing with prompt caching and context compression.
I also engineered a multimodal streaming client with asynchronous pre-decoding and video memory caching, maintaining 60 FPS during sustained scrolling. The platform supports international markets with dynamic language switching and RTL/LTR layouts, plus real-time voice interaction with an on-device Sherpa-ONNX fallback.
Before that, at Xiamen Yunhuizong Network Technology Co., Ltd., I led architecture for a commercial POS and kitchen display system, integrating peripherals through Kotlin Platform Channels. Earlier, I worked on smart campus and IoT systems, and built an Android rendering engine for interactive display hardware. My work spans native Android, cross-platform Flutter, and AI application delivery, with experience shipping products for overseas markets.
