Building software at the edge of human biology and technology, from Luxembourg.

I build software that heals,
simulates worlds,
connects people.

At ten, a film inspired by Asimov's Bicentennial Man, a robot building synthetic organs on his way to becoming human, sparked a dream: technology that heals from within.

Biomedical engineering gave that dream a name. Today I build healthcare software, VR and AI systems that bridge the gap between human biology and technology.

When I'm not shipping medical apps, I'm simulating evolution, fluid physics, or throwing themed house parties, chasing the idea that the most beautiful technology is the kind that makes us more human.

Projects

Simulations, experiments and tools, built with curiosity.

  1. How reliable are Italian politicians? Every fact-check published by Pagella Politica, gathered per politician and per party: the verdict breakdown, each checked statement linked to its article, and a score with a margin of error. A weekly pipeline rates the newer verdicts with an LLM.

    CHECK THE RADAR ↗
  2. Walk or run in the rain? Pick a pace, a wind and a rain, then walk the street: every drop is simulated and the coat darkens where it lands. Built on my paper, a fully vectorial model of directional rain exposure.

  3. Players, progress, together. A web app for volleyball clubs to track player skills, plan their development, run physical testing sessions and build training programs, all in one place.

  4. Forget the scale, trust the photo. A daily, consistently framed progress photo compared over weeks through sliders, side-by-side zoom, grids and shareable GIFs, kept private on-device.

  5. Music generated from motion. Tap play and your speed picks a mood, then every tilt of the phone reshapes the melody and chords in real time. Record a take and keep it.

    TRY IT ↗
  6. Drop in photos and a song and get a slideshow cut to the beat, the melody, the drums or the energy, with every frame centered on the faces in it and transitions from flash cuts to Polaroid stacks.

  7. Where can you stand at serve contact? Step through all six rotations of a 5-1 on a to-scale court, drag players and see the overlap rules checked live, then build legal serve-receive formations on your own.

  8. How many people live in Berlin? Guess the population of 20 big cities, then see your numbers, and everyone else's, next to the census on a 3D globe.

    React · Three.js · Firebase

  9. Particles trace flow fields shaped by noise. Switch noise types, toggle between static and evolving fields, and tune every parameter live.

  10. A petri dish where organisms evolve through natural selection in real time: DNA and gene expression, species forming and splitting, trait radar charts and family trees.

    React · Canvas API · Genetics · AI

  11. Tarot, read by candlelight. Ask a question, choose three cards for past, present and future, and an AI writes an honest reading of what they say, or reserve a seat at the live pop-up table.

    DRAW A READING ↗
  12. How hard is it to build a YC company? A reproducible pipeline scores 4,844 Y Combinator companies on a 0–100 Complexity Index that combines technical and market difficulty, explored in an interactive dashboard.
