Freelancer Overview

I specialize in AI training, LLM evaluation, and high-quality data annotation across text, image, and reasoning tasks. Over the past several years, I’ve contributed to multiple AI projects involving prompt evaluation, safety review, content classification, dialogue analysis, and structured data labeling. My bilingual proficiency (English & Chinese) allows me to handle cross-lingual tasks with accuracy and cultural nuance, especially in areas like translation assessment, natural language understanding, and generative model output scoring. My background in software engineering and AI systems gives me a strong technical foundation for tasks that require analytical thinking, consistency, and attention to detail. I’m comfortable working with complex instructions, ambiguous scenarios, and iterative improvement cycles—whether that involves testing autonomous agents, rating model responses, designing edge-case prompts, or validating long-form reasoning chains. I take pride in delivering data that is clean, reliable, and directly useful for training next-generation AI models. I enjoy fast-paced, research-driven environments and am committed to producing training data that genuinely strengthens model performance.

LLM Multi-Turn Conversation Designer & Tool-Use Simulation Specialist

Internal Proprietary ToolingTextQuestion AnsweringText Generation
I designed high-quality multi-turn conversations for training and evaluating AI assistants. This work included creating realistic dialogues between users and AI systems, modeling natural communication patterns, and simulating rich interactions across productivity applications such as calendar, email, maps, and cloud drive services. I authored both user messages and assistant responses, including accurate tool-use behaviors and corrective actions when the assistant needed to adjust its approach. Each conversation demonstrated contextual understanding, step-by-step reasoning, and smooth handling of both feasible and infeasible requests. The goal was to improve LLM performance in task completion, tool orchestration, and general conversation quality. I ensured clarity, alignment with internal playbooks, and high-quality standards through iterative revisions and collaboration with reviewers.
