About

I am a PhD in Computer Science with 3 years of experience as a data scientist, specializing in deep learning models for natural language processing and information retrieval, supported by over 5 years of dedicated research. I enjoy building end-to-end AI systems, from research prototypes to production-grade pipelines, with a focus on transformer models and retrieval tasks.

I have collaborated across international institutions, published in high-impact journals, and presented at international conferences on information retrieval and NLP for domain-specific search tasks.
