Freelancer Overview

I am an AI Response Evaluator and RLHF Specialist with over 20 years of experience in structured analysis, decision-making, and communication strategy. My background includes dual Master’s degrees in Philology and Psychology, allowing me to bring a unique blend of linguistic precision and psychological insight to AI training data projects. I specialize in evaluating Large Language Model (LLM) outputs for clarity, coherence, bias, safety, and instruction-following, with expertise in RLHF, response comparison, calibration scoring, and structured justification writing. My work spans multilingual content evaluation—fluent in Russian and Ukrainian with professional English proficiency—and cross-cultural communication analysis. I am adept at identifying ambiguity, hallucinations, manipulative framing, and implicit bias in generative AI outputs, and I excel in providing detailed, structured feedback to improve model quality, safety, and alignment. My experience in crisis psychology and behavioral decision-making further enables me to assess sensitive or high-risk content, making me well-suited for projects in AI training, prompt evaluation, and generative AI quality assurance.
