About
I’m Rajan Kumar Mahato, an AI-focused professional who enjoys building and improving datasets that help models learn more accurately, reliably, and contextually. With hands-on experience across multimodal and multilingual AI projects, I work on tasks like dataset evaluation, detailed annotation, and quality assessment to strengthen model performance and real-world usefulness.
I’ve contributed to cutting-edge AI work through remote roles with teams supporting Meta and other advanced initiatives, where I refined AI outputs for linguistic precision, alignment with user intent, and cultural relevance. Alongside training and evaluation work, I also have a technical engineering background in ML and computer vision, including projects like semiconductor wafer defect detection using YOLO.
