Freelancer Overview

With six years of experience in labeling data and training AI I specialize in computer vision and projects related to natural language processing (NLP). I excel at creating annotations for image, video and text datasets to improve the performance of machine learning models. Leading annotation teams, streamlining workflows and collaborating closely with AI research and development teams are areas where I have a proven track record in driving solutions. My notable projects involve annotating a number of images for self driving car applications, which notably enhanced detection accuracy. Additionally I have overseen NLP model evaluations to improve language comprehension. Proficient in using tools like Labelbox, CVAT, Prodigy and AWS SageMaker Ground Truth underscores my attention to detail and problem solving abilities when managing datasets. These qualities set me apart in the field. Position me as an asset, for any AI focused project.

Labeling Experience

Code Snippet Classification for Automated Code Review

MindriftTextComputer Programming Coding

Worked on a project to classify code snippets and functions for an automated code review system. Annotated various programming languages and frameworks, labeling code snippets based on functionality, complexity, and potential vulnerabilities. This data was used to train machine learning models to identify code patterns and suggest improvements or highlight potential issues in real-time.

Self-Driving Car Image Annotation

CVATImageBounding BoxObject Detection

Led a team to annotate over 100,000 images for a major self-driving car project. Utilized bounding boxes to label vehicles, pedestrians, traffic signs, and other relevant objects in urban and highway environments. The project significantly enhanced object detection accuracy by 25%, contributing to the development of safer and more reliable autonomous vehicles.
