Freelancer Overview

I’m a native Mandarin speaker fluent in both Simplified Chinese and English, passionate about language accuracy and clear communication. I’ve worked as an AI Data-Labeling QA Reviewer for Mandarin content with Mindrift, where I reviewed and refined linguistic data used to train AI systems. That role sharpened my attention to detail, quality control, and ability to follow precise transcription and annotation guidelines. Alongside my language expertise, I have a background in software development and AI, which gives me a strong understanding of how accurate data supports machine learning and natural language processing. I take pride in being reliable, disciplined, and consistent with deadlines, whether it’s transcribing Mandarin audio, validating content, or ensuring data accuracy at scale. I work from a quiet environment with stable internet and professional audio equipment, ready to contribute several hours daily. I can start immediately and would love to support your team with precise, high-quality Mandarin transcription or QA work.

In this project, I will compare two search engine results pages (SERPs) for the same user query. My task is to assess the quality of the results on each SERP, and then decide which SERP performs better overall, or if they are equally good or poor.
