Selected projects / A closer look

Projects you can explore and try for yourself.

012026Digital menu & café management

Café Fink

I built a website for Café Fink in Oberbozen with a digital menu in German, Italian, and English. Guests can order multiple items and select their table on a floor plan. Once signed in, the café team can update images, copy, and prices, publish the menu, or download it as a PDF. They can also arrange rooms, tables, and furnishings on the floor plan. Open orders appear at the relevant table and can be marked complete after being entered into the point-of-sale system. The team controls when online ordering is available. These screenshots show a local preview with sample orders.

SignMirror

SignMirror was my final project for the CAS in Advanced Machine Learning for Software Engineers. I developed the Python AI model with Sasa Gazikalovic. It compares live camera footage with a reference video using detected hand and body landmarks, while letter mode gives immediate feedback on how closely a gesture matches.

SolarPlaner

This app lets users manage roofs and module types, then place solar panels on roof images manually or automatically. Spacing and margins can be adjusted, and an overview shows the planned layout.

Origins / South Tyrol to St. Gallen

They shaped how I approach problems: understand the terrain, then move with purpose.
