Freelancer Overview

I am a data-driven researcher with hands-on experience in data labeling, annotation, and AI training data pipelines, especially in the context of large-scale scientific and astronomical datasets. My work spans developing and applying machine learning algorithms—including CNNs and clustering methods—for image and spectroscopic data classification, anomaly detection, and regression tasks. I have created and curated balanced datasets of over 150,000 galaxy images for morphological classification, annotated spectroscopic anomalies in SDSS data, and handled multi-modal data from telescopes and surveys. My technical toolkit includes Python (Numpy, Pandas, Scikit-learn, TensorFlow, OpenCV), PyTorch, and data visualization tools, along with experience in cleaning, organizing, and validating complex datasets. I am meticulous and detail-oriented, with a proven ability to optimize annotation processes and ensure high data quality for AI model development, with strong skills in scientific writing and collaborative research.
