Freelancer Overview

I am a Computer Science student who is passionate about Artificial Intelligence (AI) and Machine Learning (ML), specifically in the context of creating and labeling training data sets. My previous academic courses and projects have enabled me to work with structured data sets, perform text classification, and use feature extraction techniques such as TF-IDF to gain insight into how high-quality labeled training data can directly affect the accuracy and performance of models. I have an understanding of how to be detail-oriented in following designated annotation guidelines for consistent and accurate labeling. I have worked with CSV and JSON type datasets and have done validation of those datasets, as well as quality checks. With my academic knowledge of AI/ML concepts and my ability to process data, I will be able to assist with AI training data workflows.

Labeling Experience

Audio Data Labeling for Voice Detection AI System

AudioClassification
I contributed to a voice detection AI system by labeling and classifying structured audio datasets. Tasks included reviewing and annotating audio segments for voice activity or speaker identification. I ensured all data met quality standards before use in model training. • Labeled audio samples for voice activity presence • Applied speaker classification tags as needed • Validated audio labels and reviewed ambiguous cases • Supported training data preparation for classification pipeline
