Freelancer Overview

I have hands-on experience in AI training data workflows, with a focus on prompt evaluation, front-end UI annotation, and media content labeling. With a background as a Front-End Developer and Prompt Engineer, I bring technical precision and contextual understanding to labeling tasks involving HTML/CSS components, user interface structures, and interactive behavior. My attention to detail and ability to recognize design patterns make me effective in annotating complex web interfaces and identifying inconsistencies in UI/UX data. I have worked on AI prompt structuring and evaluation, where I assessed the accuracy, clarity, and tone of large language model (LLM) outputs. I also have niche expertise in annotating media content for genre classification and emotional tagging, particularly in Indian cinema targeting international audiences. My ability to bridge both technical and creative content labeling makes me a strong contributor to high-quality training datasets for AI models.
