Key Skills

Freelancer Overview

I am a Data Scientist with hands-on experience in data preparation, quality control, and machine learning model development, particularly within dynamic startup environments and academic research settings. My work has involved preparing and validating high-quality datasets for projects such as sales optimization in retail, early warning systems for debt default, and credit risk modeling, where attention to data accuracy and annotation was critical. I am proficient in Python (Pandas, Polars, Scikit-learn, TensorFlow, PyTorch), R, SQL, C++, and Matlab, and have built ML algorithms from scratch for applications including computer vision (gaze estimation, CAPTCHA recognition, gesture and spoken digit recognition) and simulation projects. My background in teaching and research further strengthens my ability to handle complex data annotation tasks and ensure robust, reliable AI training data.
