Freelancer Overview

I bring a strong blend of hands-on AI training experience and data-focused operational expertise, built over several years working with high-volume, enterprise-grade workflows. In my current and recent roles as an AI Trainer and Junior Team Lead at Invisible Technologies, I have directly contributed to training and improving AI models by evaluating outputs for accuracy, refining prompts, and delivering structured feedback to enhance performance and reduce errors. My work goes beyond basic annotation, incorporating quality evaluation, trend analysis, and collaboration with cross-functional teams to ensure AI outputs align with client expectations. What sets me apart is my end-to-end understanding of training data pipelines, supported by a strong foundation in data research, validation, and CRM data management. I combine technical skills such as prompt development, data analysis, and reporting with operational strengths like SLA adherence, documentation, and workflow optimization. Additionally, my experience leading teams and supporting B2B clients allows me to contribute not just to AI training tasks, but also to improving processes, maintaining quality standards, and scaling efficient data operations

I worked on an AI evaluation project where I reviewed and improved AI-generated responses. My role involved assessing outputs for factual accuracy, writing quality, structure, and formatting, including the use of Markdown and LaTeX. I rewrote responses to improve clarity, tone, and overall effectiveness while following a detailed evaluation rubric. The work required strong editing skills, attention to detail, and consistency when handling high volumes of content to ensure the AI outputs met high-quality standards

I worked on an RLHF project focused on evaluating video-based feedback. Instead of just text, we reviewed video outputs or recordings and assessed how well the AI performed based on human expectations. We would watch videos and rate or rank them based on criteria such as relevance, clarity, accuracy, and the overall quality of the response or behavior shown.
