Freelancer Overview

I am a software engineer with a strong background in AI/ML development and training data workflows. My experience includes building and deploying models in PyTorch, TensorFlow, and scikit-learn, with applications in image recognition, text sentiment analysis, and probabilistic decision-making frameworks. Through both academic projects and professional engineering work, I’ve developed a deep understanding of how high-quality training data directly impacts model accuracy and reliability. What sets me apart is the combination of technical AI expertise and hands-on project experience. I have built CNNs for image classification, RNNs for NLP sentiment analysis, and applied Bayesian inference with Markov Decision Processes for decision-making under uncertainty. These projects required not only coding but also careful data preparation, annotation, and validation — giving me the skills to deliver precise, consistent, and useful AI training data. My background in software engineering also ensures I can work efficiently with labeling tools, version control, and collaborative workflows to maintain data integrity across projects.
