Hi 👋, I'm Mateusz Janowski

Computational Engineering student focused on AI, machine learning, and intelligent software systems.

NYXMatik

🧠 What I Do

  • 🧪 Designing machine learning and deep learning workflows using Python, scikit-learn, TensorFlow, and PyTorch
  • 📊 Specializing in data analysis, information retrieval, and hybrid semantic search systems
  • 🏥 Building production-level full-stack solutions using .NET (C#), Angular, and REST APIs (e.g., Hospital Management System)
  • 🤖 Developing explainable and performance-tuned ML models (e.g., MLPs, GAMs, ensemble methods)
  • 🧠 Integrating Prolog and classical logic into system-level planning (e.g., surgery room scheduling)
  • 🎓 Studying at AGH University and currently completing Erasmus+ at ISEP Porto

🎓 Education
