What I'm looking for

I seek opportunities in AI training and data quality assurance, focusing on innovative projects.

I am an experienced data annotator with a strong background in AI training and evaluation. Since 2023, I have honed my skills in various aspects of data annotation, including speech transcription, video/image annotation, and semantic segmentation. My work at HengYiDe Tech involved image data cleansing and semantic segmentation, where I utilized advanced tools tailored for deep learning applications.

Throughout my career, I have collaborated with notable clients such as Google and Tencent, focusing on multilingual datasets and machine translation quality assessment. My role as a Model QA Evaluation Specialist allowed me to assess AI response quality and ensure the accuracy of machine translation outputs. I am passionate about enhancing AI/ML data quality through my linguistic knowledge and foundational computer science skills.
