Freelancer Overview

I am a results-driven software engineer with hands-on experience training and refining large-scale AI models through data labeling and annotation of both text and video. My work has focused on improving AI reasoning, dialogue, and contextual accuracy by evaluating outputs, identifying hallucinations, and enhancing model reliability for real-world applications. I have collaborated with cross-functional teams to design and optimize prompt strategies and have contributed to projects in conversational AI, logistics management, and internal enterprise platforms. My technical toolkit includes Python, C#, Java, SQL, Docker, and CI/CD pipelines, and I am skilled at following detailed guidelines to produce high-quality training data that drives better user engagement and AI performance. Passionate about interactive storytelling and immersive experiences, I bring a strong attention to detail and a commitment to advancing AI capabilities.
