Freelancer Overview

I am an adaptable and detail-oriented data professional with hands-on experience in data labeling, annotation, and database management for AI training and analytics projects. My work as a freelancer at RWS involved executing data collection, annotation, and object tagging tasks to enhance dataset quality for machine learning, with a strong focus on accuracy and usability. My commitment to quality, and continuous learning enables me to consistently deliver high-quality results in fast-paced environments.

Labeling Experience

Diamond Project

Internal Proprietary ToolingImageSegmentationClassification
This data annotation project included tasks of pairwise comparisons, counting tasks, and object tagging tasks, which included audio, video, and/or images as content or data collected. In one part of the project, I imported pictures from instagram, tagged the people in them, labelled the locations, their attires and other visible adornments. After, I searched the internet for other pictures from those same locations, other people wearing those same outfits and other pictures of the visible adornments. I then combined everything to submit on the external client platform, accessible through credentials provided by the hiring company.

Diamond Project

This data annotation project included tasks of pairwise comparisons, counting tasks, and object tagging tasks, which included audio, video, and/or images as content or data collected. One part of the project requred me to compare two AI generated videos to the original and choose which is the better replica of the original video. I compared the videos frame by frame for subtle differences, took into account the video qualities and length of videos to judge which of the generated videos looks more like the original.

Ruby project

This project required me to judge by accepting or rejecting with valid reasons how well an AI generated face swapped pictures matched respective given prompts. I had to point out generated images that don't follow logic such as a man's head on a woman's body, complexion of faces not matching that of the rest of the body etc. I did all these keeping in mind the prompt given.
