What I'm looking for

I’m interested in contributing to the development, evaluation, and safety of modern AI models through flexible, remote, guideline-driven work.

On independent contract projects, I evaluate AI-generated outputs for accuracy, relevance, clarity, safety, and consistency, following project guidelines.

I annotate and label text, audio, images, video, and collected datasets. My work includes pairwise comparisons, ranking, counting, transcription-quality checks, and object tagging.

Across University Projects and Independent Practice, I assisted with collecting, cleaning, preprocessing, reviewing, and quality-checking data for AI and machine learning projects.

I use Python, Pandas, and NumPy alongside tools such as Label Studio and CVAT to organize data and support evaluation workflows. I’m interested in contributing to the development, evaluation, and safety of modern AI models.
