Mechatronics Engineer & AI Enthusiast.
Building intelligent solutions with Python, LLMs and Deep Learning.
Education & Thesis
Budapest University of Technology and Economics, Mechatronics Engineering MSc
Fine-tuning GPT models
Reviewed AI and NLP literature and I have fine-tuned BERT, GPT-2, T5 and Llama2 models on two different health databases (one of them was made by me) and evaluated the responses generated by the models and compared the original and the fine-tuned models using different methods.
University of Debrecen, Mechatronics Engineering BSc
Development of a robotic hand for performing unique grasping movements
I designed and 3D-printed a robotic hand capable of mimicking human gestures. Developed custom PCB and programmed in C++.
Hobbies & Free Time
My interests lie at the intersection of creative technology and pop culture. I enjoy delving into AI-based developments and professional courses to constantly broaden my horizons. The rest of my free time is filled with my passion for Japanese culture, the world of quality films and music, which always provide me with spiritual refreshment.
