## About

```text
At the Regulatory Authority for Energy, Waste and Water, I developed internal information systems and software solutions, including NLP software. I also provided technical support and developed desktop applications to support internal workflows as a contractor through Byte Computer.

On Arealyse, I developed a real estate discovery platform with personalized property search and machine learning models for property value estimation. I also performed web scraping and regional data analysis.

My machine learning projects include predictive models for industrial sensor data, with 95% accuracy, and classification models for obesity level estimation, with 97% accuracy. I also developed an NLP system to reconstruct incomplete legal documents from Greek-language text.

I studied Computer Science at the University of Piraeus School of Information and Communication Technologies, where my thesis focused on deep learning for brain tumor classification and segmentation from MRI images. I’m pursuing an M.Sc. in Data Science and Machine Learning at National Technical University of Athens (NTUA), and I placed first in the 2025 NLP University Competition.
