Kajen Cullen

I am an AI engineer and mathematics expert with over two years of experience building deep learning and reinforcement learning products. I focus particularly on the development of RAG-based chatbots and conversational agents, as well as computer image processing.
I have experience developing LLM-based applications, RAG systems, document intelligence platforms, and scalable ML pipelines using PyTorch and cloud technologies.
I enjoy solving complex problems by combining machine learning, backend engineering, and AI system design to create reliable, real-world applications.
