Hi 👋, I'm Hermès

CS student in Basel, Switzerland — building practical projects with Python, Java, C++, web tech, and embedded systems.

I'm interested in software engineering, data science, creative AI, algorithms, and small tools that solve real problems.
Right now, I am using GitHub to document projects properly, clean up older experiments, and build a portfolio that shows how I work.

  • 🔭 Currently working on AI/music generation, embedded transport displays, algorithm visualizations, and automation tools
  • 🌱 Currently learning machine learning workflows, Java software design, data science, and numerical methods
  • 🛠️ I like building small complete projects with docs, demos, tests, and clean repository structure
  • 💬 Ask me about Python, Java, GitHub Pages, ESP32 projects, algorithms, or project documentation
  • 📫 Reach me at hermesnathanheiniger@gmail.com
  • 👨‍💻 My projects are available here: github.com/HerRei
