Freelancer Overview

I am a data scientist and machine learning engineer with extensive experience in data annotation, preprocessing, and the development of high-quality AI training datasets, particularly in computer vision and medical imaging domains. My background includes designing and implementing deep learning pipelines for object detection, semantic segmentation, and image classification, where I handled large, complex datasets, performed data cleaning, labeling, normalization, and feature engineering using Python, TensorFlow, PyTorch, OpenCV, and Pandas. I have led projects involving self-supervised learning, built custom data pipelines for healthcare and autonomous vehicle applications, and collaborated closely with cross-functional teams to ensure accuracy and integrity in labeled data. My work has contributed to real-time image enhancement, anomaly detection, and medical diagnosis, and I am passionate about building robust datasets that power reliable AI systems.

Subject Expert

MercorTextComputer Programming CodingPrompt Response Writing SFT
Served as a Subject Matter Expert on an LLM evaluation and instruction-tuning project involving high-quality text data, focusing on computer programming and prompt-response writing for supervised fine-tuning (SFT). Reviewed and produced technically accurate prompt–response pairs, evaluated model outputs for correctness, reasoning quality, and adherence to project rubrics, and provided structured feedback to improve response quality and consistency. Worked within Mercor’s labeling environment to maintain high quality standards across diverse programming and prompt-engineering tasks while supporting reliable data generation for model improvement.
