Machine learning & software development
High-school student at Tudor Vianu National Informatics College in Bucharest, focused on machine learning and software development.
National AI-olympiad medalist and Kaggle competitor. Co-founded and built Vianu AI, the learning platform and curriculum for the school's AI club, teaching it with two classmates.
Largely self-taught, since AI is still new as a school subject in Romania.
Android app for texting friends and calling for help at festivals when the mobile network goes down. Messages hop from phone to phone over Bluetooth, without internet or an account, and stay end-to-end encrypted. My idea; I built a large part of it with team Downtown Fitness. It won VNU Hack 2026, and we presented it on stage at How to Web.
Learning platform for the AI club at Tudor Vianu National Informatics College in Bucharest. Built in Next.js and TypeScript. On the dev team behind most of what's live: lessons with runnable code, a curriculum from Python basics to deep learning, and olympiad tips from students who competed.
AI résumé checker: upload a CV, get it scored with specific fixes. Built with Next.js, Claude, Supabase and Stripe. Works end to end; hosting is paused.
Romania's national AI olympiad, run by the Ministry of Education and the national AI hub. Build and train models scored against held-out data. Bronze at the national final, April 2026.

23-hour NLP hackathon at the University of Bucharest, run by the Nitro association: 73 teams, a fresh Romanian-language dataset, a live leaderboard. Finished 17th, 2026.
Kaggle simulation competition: program a bot for a real-time strategy game where fleets capture planets orbiting a sun, ranked on a ladder of live 1v1 and 4-player matches. Built a tensorized planner, tuned on real ladder losses instead of self-play.
Kaggle competition to build the smallest neural network that still solves ARC-AGI reasoning tasks, trading parameter count for accuracy. Team San Francisco, 2026.
Kaggle competition predicting the rock a well drills through from its sensor logs, the kind of model used to automate oil-and-gas drilling. Team Silicon Valley, 2026.
National applied-informatics olympiad, System Interoperability section: networks, services and protocols. County stage, 10th grade, March 2026.
First year in the applied-informatics olympiad, same System Interoperability section. County stage, 9th grade, March 2025.
