Freelancer Overview

I have strong experience in AI training and data labeling through projects with Outlier, Alignerr, and Appen. My work covers a wide range of tasks including RLHF evaluation, localization, prompt creation, text and audio annotation, and image comparison. I’ve contributed to improving large language and vision models by assessing accuracy, tone, photorealism, and overall prompt relevance. What sets me apart is my dual background in marketing and linguistics. I combine analytical precision with a deep understanding of natural language and cultural nuances. I’m detail-oriented, consistent with complex guidelines, and skilled at providing high-quality human feedback across multiple AI domains.

Image comparison

Scale AIImageEvaluation Rating
I'm working on an image comparison project where each task included a prompt and two AI-generated images. My job was to evaluate which image best matched the prompt based on several criteria such as photorealism, visual flaws, composition quality, and overall relevance. The goal was to help improve image-generation models by providing consistent and precise human feedback on visual content.

RLFH

At Outlier, I worked on a Reinforcement Learning from Human Feedback (RLHF). My role was to review and rank AI-generated responses based on accuracy, clarity, tone, and adherence to user intent. I analyzed multiple model outputs, selected the best ones, and provided feedback to help fine-tune large language models. This project required strong analytical skills, linguistic precision, and consistency in applying complex guidelines.

Voice Acting

I participated in a voice acting project where I recorded natural speech based on given script. The goal was to produce clear, expressive, and realistic audio samples for training text-to-speech and speech recognition models. I focused on delivering natural intonation, consistent pacing, and correct pronunciation to help improve the model’s ability to understand and generate human-like speech.
