  3. StrongArm

    07/2026

    Personal project

    A real-time, 1v1 arm-wrestling game where precision and timing decide the winner.

    Inspired by The Outlast Trials, players compete in three mini-games to pull a shared power bar to their side. I built the game server entirely in Rust, with a Next.js frontend, Socket.IO for real-time play and automated Docker deployments.

  5. Learn2Slither

    42 school project

    An AI that teaches itself to play Snake through reinforcement learning.

    Trained with Q-learning and a hand-rolled Q-table: the snake only sees 4 rays around its head and learns from rewards. The game, SDL3 interface and argument parser were all written from scratch in C++.
