About

Lionel Fragnière

Based in Switzerland, I navigate between writing, development and photography. Specialized in GIS, GeoAI and machine learning, I build geospatial data pipelines as well as modern web applications — and I tell stories, whether through code, words or the lens.

I’m currently writing my first novel, Monthey sous pression, and developing solutions combining artificial intelligence and geospatial analysis.

Work in progress

My first novel, rooted in Monthey.

Julius keeps his key. The Tsevarin watches. Monthey counts in the shadows.

Dive into a universe where mystery intertwines with the history of a Swiss town. A story that weaves fiction and reality, between ancient alleys and well-kept secrets.
