Senior Java engineer at Visable who built its high-concurrency search and advertising system from scratch.

China

Message

At Visable, I built the core search and advertising system from scratch, integrating ad delivery with search recall and ranking. Its core search API maintained P99 latency below 200ms.

At NetEase Cloud Music, I developed backend systems for core social features on a tens-of-millions-user platform. I also designed a message retry framework that addressed failures causing financial loss and user complaints.

At Capgemini, I implemented Harness Engineering practices for P&G's ad delivery project. Requirement rework fell by 50%, and generating multi-feature test strategy documents became about 60% more efficient.

Earlier, I rebuilt a payment center's core transaction flow at Hangzhou DtDream Technology Co., Ltd and worked on data warehouses and ETL pipelines at Zhejiang Insigma Hengtian Software Ltd. I bring Java backend, full-stack, data warehouse, and AI engineering experience.
