Freelancer Overview

I have a strong background in AI-driven systems, machine learning, and data processing, with hands-on experience in developing and deploying solutions that rely on high-quality training data. My academic research has focused on computer vision and remote sensing, including projects where I performed data pre-processing, annotation, and feature engineering for fire risk assessment and intrusion detection using CNNs. I am skilled in Python, TensorFlow, PyTorch, and Scikit-learn, and have worked extensively with both field and satellite data, as well as image and text datasets. My experience spans building and optimizing machine learning models, hyperparameter tuning, and ensuring data quality for robust AI performance. I am passionate about leveraging my technical and analytical skills to contribute to impactful AI projects that depend on accurate and well-labeled data.
