Useful things.
Room for the unexpected.

I build tools for images, music, machines, and the occasional everyday problem. Some begin in a university course; others begin with something I want to understand a little better.

  1. 01 / Image restorationDesktop alpha
    Colorful balconies of the Unité d'Habitation in Marseille, enlarged with LocalSR.
    A real LocalSR output. Photograph by Tim Ziegelbaum. About the image.

    LocalSR

    Give a photograph more room. A desktop application for image enlargement, denoising, and deblurring, with models that run on your own computer.

    Tauri / Svelte / Python / PyTorch

    Alpha software. Image comparison and platform details in the showcase; HAT-S and HAT-L face experiments are documented for a later release.

  2. 02 / Environmental dataLocal research tool
    Basel-Stadt, Switzerland

    Nature,
    in the details.

    Inventory changes / Maps & queries

    A study of change in the canton's nature inventory.

    Nature Inventory Delta

    What changes between two versions of a nature inventory? A local interface for exploring Basel-Stadt's data through maps, charts, and optional language-model queries.

    Python / FastAPI / Streamlit / SQLite

    Requires a prepared inventory database, which is not included in the repository.

    PhantomHunt

    An asymmetric, three-versus-one Java game made at the University of Basel. My work focused on networking, lobbies, game-state synchronization, and scoring.

  7. 07 / AlgorithmsUniversity project

    Small paths, better routes

    An ant-colony visualizer for the traveling salesperson problem. Adjust the parameters, watch tours develop, and experiment with random cities or New York landmarks.

  8. 08 / Everyday toolsPractical application

    A little less bookkeeping

    A guided entry flow for a recurring bookkeeping task. Configurable choices turn repeated typing into structured records sent to Google Sheets.

02 / A little about me

A technical mind.
A curious eye.

I'm a computer science student at the University of Basel, based in Sissach. Before that, I spent a year studying mechanical engineering at ETH Zürich.

I'm interested in how software meets the physical world: a model turning pixels into an image, a tiny display waiting for a train, or a few lines in a terminal making a machine easier to understand.
