Object Detection

Freelancer Overview

I have hands-on experience in data labeling and AI training data through university projects focused on object detection using aerial imagery. These projects involved annotating and processing datasets to identify and classify objects such as vehicles, machinery, and people, ensuring high-quality data for machine learning models. Working with tools and frameworks for image processing allowed me to gain a solid understanding of data preparation workflows and their importance in improving model performance. Through these academic projects, I developed key skills in attention to detail, data organization, and problem-solving while working with large datasets. My exposure to real-world challenges in object detection has equipped me with a strong foundation in creating accurate and reliable training datasets, which are critical for the success of AI models. I am eager to apply and expand these skills in professional environments.

I worked on refining AI-generated responses based on initial prompts, ensuring they met a defined set of quality and content requirements. My responsibilities included evaluating and improving generated answers, especially for programming-related queries, comparing multiple outputs from different models, and selecting or rewriting the most accurate and helpful response. I also created step-by-step explanations to help users understand how to solve technical problems effectively.
