I worked on an AI training project with Revelo, where I contributed to improving the performance and accuracy of machine learning models through data annotation, evaluation, and quality assurance tasks. My role involved analyzing AI-generated outputs, identifying errors, and providing structured feedback to enhance model reliability and alignment with real-world use cases. I worked with diverse data types, including text and structured datasets, applying critical thinking and attention to detail to ensure high-quality training data. This experience strengthened my understanding of AI systems, model behavior, and the importance of human-in-the-loop processes in building robust and scalable artificial intelligence solutions.
