About Me

Welcome to my portfolio! I’m a recent Master’s graduate in Natural Language Processing with strong skills in Python, Data Science, and Machine Learning. I specialize in building AI-powered applications and have a passion for transforming complex data into actionable insights.

During my academic journey, I have worked on several projects — from developing chatbots to extracting structured information from industrial documents — which allowed me to acquire both technical expertise and problem-solving skills.

When I’m not coding, I enjoy exploring new technologies, learning about business and e-services, and practicing combat sports to keep a balanced and disciplined mindset.
