Freelancer Overview

I am passionate about working with data to build and support high-quality AI solutions. My experience includes hands-on projects where I performed extensive data preprocessing, cleaning, and feature engineering to prepare datasets for machine learning models. I am skilled in using Python, along with libraries like NumPy, Pandas, and Scikit-Learn, for tasks such as data annotation, visualization, and analysis. In my projects, I have handled both tabular data and regression tasks, optimizing models and evaluating their performance using metrics like RMSE and R². I am proficient with tools such as Jupyter Notebook, Google Colab, and GitHub, and I am comfortable collaborating in team environments. My strong problem-solving skills and adaptability make me well-suited for data labeling and AI training data roles, where attention to detail and data quality are essential.
