About
I am an AI Engineer and AI Research Fellow specialising in practical AI systems across LLMs, RAG, agentic AI, multimodal AI and document intelligence. My research focuses on fact verification of health information, information extraction using large language and vision-language models, and AI for document and process understanding. I thrive on turning research ideas into working systems, demos and reusable pipelines, and on contributing to the open-source community. I also co-founded Khyontek AI, building SME-focused AI products.
