About

I build AI systems that people actually use. Most days that means building production AI systems as an engineer at Focus AI, plus a small team of agents on a server at home that keeps working while I am at school.

Before that I built SeizAI, an epilepsy detector trained on EEG recordings. At Jonk Fuerscher, Luxembourg's national science contest, it won me a trip to Google in Paris. I am finishing A Levels in Luxembourg and will study Computer Science at university from 2027.

  • SeizAISeizure detection from EEG signals: a CNN, a real-time web app and an Arduino prototype.2026 · Google Paris trip

    A CNN that classifies 8-second EEG windows as normal or seizure, trained on the CHB-MIT dataset (23 patients, 900+ hours, 198 seizures). A Gradio app shows detection live, and an Arduino prototype switches from a green LED to a red LED and buzzer when a seizure is flagged.

  • MOIENAn AI money coach for teenagers in Luxembourg, built in 48 hours.2026 · Coup de Cœur

    Built with my team at the 10th LTS FinTech Hackathon. A working app, not slides, which won the jury's Coup de Cœur prize.

  • LegionA home server where my AI agents work around the clock.ongoing

    One machine running 20+ scheduled jobs: a second brain that captures and files what I learn, hourly snapshots with offsite backups and regular restore tests, two virtual machines and a few Docker stacks. Claude Code, Codex and Grok agents work on it in parallel, each with a hard memory limit so nothing takes the machine down. This website was built there.
