Applied Scientist

Amazon AWS AI Labs

I am an Applied Scientist in Natural Langauge Processing (NLP) at Amazon AWS AI Labs. My research interests include question answering, conversational agents, patterns-based few-shot learning, distant supervision, cross-lingual and cross-domain transfer. Before joining Amazon, I was a Research Scientist at Checkstep Research, where I worked on NLP for content moderation using few-shot learning, semi-supervised and multi-source fine-tuning of pre-trained language models. I did my Ph.D. at Sofia University “St. Kliment Ohridski” on dialog and question answering systems.

I have a strong software engineering background along with extensive experience in developing production systems. I previously held a position as a Machine Learning Engineer at ReceiptBank (now Dext) where I built NLP models for automatic field information extraction from unstructured payment documents. I was also a Machine Learning Engineer in an ad-tech company, Adcash OÜ, where I developed distributed and scalable models for ad recommendations. Prior to that, I created and maintained desktop and web applications while in the roles of a full-stack Software Engineer and Team Lead at Acstre.
