Hi đź‘‹
I’m Maiia Kotyga, a data analyst and AI specialist focused on machine learning,
mathematical modeling, NLP, and healthcare digitalization.
My work combines analytical and ML-based solutions, data infrastructure, applied research,
and educational projects. I have a background in mathematics and IT, and experience
in product, technology, and research contexts.
My current research interests include efficient LLM inference, with a particular focus
on dynamic context-dependent pruning methods.
I teach and mentor in AI, NLP, and data science, support hackathon and olympiad teams,
and create educational materials for students and early-career ML practitioners.
In short: a human teacher for machine learning 🤖.
