Freelancer Overview

I’m an AI data trainer with hands on experience creating and evaluating prompts, reviewing model outputs, and performing detailed annotation tasks across multiple domains. I’ve worked on projects through DataAnnotation.tech and other platforms, which covered LLM evaluation, Model stress testing, translation assessment, factuality checks, image annotation, and prompt rewriting. My strengths include crafting high-quality, bias-free prompts, analyzing AI-generated text for accuracy and naturalness, and applying consistent judgment across complex linguistic and visual data. I bring a strong attention to detail, excellent written communication, and a solid understanding of how large language models are trained and evaluated.
