Freelancer Overview

Experienced data labeler with a strong background in supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF) projects at Scale AI since March 2025, specializing in Russian-language datasets. Proficient in prompt engineering, model response evaluation, and localization, with a keen eye for cultural nuance and linguistic accuracy. Skilled in crafting and refining prompts, defining ideal response criteria, and performing comparative analysis to ensure high-quality AI outputs, with additional expertise in voice data recording and speech recognition tasks. My ability to deliver precise annotations, provide actionable feedback, and adapt content for the Russian speaking audience sets me apart in enhancing AI model performance.
