Freelancer Overview

I have experience working with data used to train AI, through data collection, cleaning, validation, and quality checks. Most of my work has involved reviewing large datasets, checking accuracy, consistency, and relevance, and making sure the data meets project rules before it is accepted. I am used to working with survey data, open-ended text responses, and structured datasets, where careful labelling and clear judgement are required to maintain quality. I bring a strong analytical mindset, with skills in identifying patterns, outliers, and low-quality responses that could affect model performance. My background in data analysis helps me understand how labelled data is later used in training and evaluation, so I focus on clear guidelines, and repeatable decisions. I work well with written instructions, handle repetitive tasks with focus, and deliver consistent results even on high-volume projects.

I searched for images and carefully identified the main entities present in each image. This involved observing details such as objects, people, actions, and settings, and clearly defining what each entity represented. I then looked for similar entities or moments across different images, ensuring they matched the required criteria and context.
