Freelancer Overview

I am a results-driven machine learning engineer with hands-on experience in data labeling, data annotation, and AI training data preparation across various domains, including natural language processing, medical diagnostics, and content moderation. My background includes designing and implementing end-to-end ML pipelines, where I have performed extensive data cleaning, preprocessing, feature engineering, and supervised/unsupervised labeling for projects such as malware detection, malaria diagnosis, hate speech and sarcasm detection, and emotion classification from text. I am skilled in Python, Scikit-learn, TensorFlow, HuggingFace Transformers, and have utilized tools like Streamlit and Flask to build user-friendly data annotation interfaces. My approach emphasizes data quality, model explainability, and actionable insights, ensuring that annotated datasets are robust and drive high-performing AI solutions. I am passionate about leveraging my technical and analytical skills to support the development of reliable, ethical, and impactful AI systems.

Labeling Experience

Kinyarwanda Hate Speech Detection — Sentiment Annotation

OtherTextClassification
Labeled thousands of Kinyarwanda-language text samples with sentiment and toxicity tags to train a hate speech detection classifier. Paid close attention to cultural and linguistic nuance while adhering to annotation style guides and consistency requirements. Delivered large, high-quality labeled data batches for model training evaluation. • Focused on an underrepresented African language (Kinyarwanda) for NLP. • Emphasized subjective content labeling for hate speech detection. • Maintained accuracy through self-QA and batch-level review. • Supported supervised learning project workflows for sentiment annotation.

Freelance Data Annotator / AI Trainer

OtherVideoClassification
Annotated a large-scale Kinyarwanda-language sentiment analysis dataset to support hate speech detection model training. Labeled thousands of text samples for sentiment polarity, toxicity, intent, and emotion categories based on detailed annotation protocols. Enabled high-quality, low-resource African language NLP research by delivering consistent annotation batches. • Applied structured labeling for both binary and multi-class NLP tasks. • Used Atlas Capture to perform sentiment and emotion annotation. • Performed entity recognition and span-labeling within text datasets. • Ensured dataset quality via thorough self-QA and peer review.

Text-Based Emotion Detection — Multi-Class NLP Annotation

OtherTextEmotion Recognition
Annotated written text across six discrete emotion labels for a supervised emotion classification model. Used systematic annotation protocols and documented emotions for each text instance to ensure data quality and reproducibility. Participated in internal dataset reviews to verify the reliability of the emotion annotation process. • Covered core emotion categories: joy, anger, sadness, fear, disgust, and surprise. • Maintained consistency by following established labeling rules. • Performed detailed documentation of annotation decisions. • Focused on multi-class labeling for fine-tuned NLP emotion models.
