At ByteDance, I partner with policy and engineering teams on TikTok Safety model evaluation, translating policy into risk signals and validation criteria. I designed a reusable AI workflow that reduced scenario delivery time from about five business days to one.
On Yijian AI Digital Wardrobe, I independently took an AI web application from requirements and design through model integration, testing, and deployment. I used feedback from a 50-user beta test to reprioritize the roadmap and complete a V1.1 iteration.
