Experiences

Algorithm Assistant Intern | Deep Talent Company Ltd.

Sept. 2025 – Present · Hefei, China

Led development of an agentic-AI talent-acquisition platform, accelerating the core pipeline about 50% and scaling it to roughly 10k concurrent users.

Leveraged Chrome DevTools Protocol (CDP) to instrument headless browsers in real time for deterministic, reproducible agentic-AI workflows.

Prototyped unified web-automation frameworks, redesigned chat-file formats with backward-compatible search, and parallelized execution across four platforms for real-time frontend updates.

AI Product Engineering Intern | Hefei Youchuanghui Tech. Co., Ltd.

Mar. 2025 – Aug. 2025 · Hefei, China

Developed a batch-scheduling pipeline for AI irrigation that scaled to 50K+ jobs per day, reduced peak load about 68%, and saved about 30% water in pilots.

Built a one-click prototype flow that turns a single prompt plus five business questions into deployable front-end code so non-technical users can ship production-ready apps faster.

Implemented a real-time speech-to-speech customer-service Voice AI backend using OpenAI APIs with LiveKit orchestration, targeting sub-500 ms conversational latency.

Back End Developer Intern | Help Bridge

Dec. 2022 – Feb. 2023 · Hong Kong
