Roee SivanSoftware Engineering student & builder

Over the past year I shipped an open-world game in both Unity 6 and Unreal Engine 5, a course-review platform used by 199 students at my university, two browser games running on Three.js and canvas, a computer-vision pipeline that analyses table tennis matches frame by frame, and a reinforcement-learning project that taught a quadruped robot to walk in simulation. My work spans real-time 3D, full-stack web, and applied machine learning, and every project here is live, open source, or both.

Selected work

Six builds across real-time 3D, production web, computer vision and reinforcement learning. Each one has a case study, and all of them are live right now.

  • The Block key art: a cel-shaded coastal city at sunset, palm-lined beach highway with a rider on it, a helicopter and a jet ski over the water.

    The Block

    2026

    A GTA-style open world, built in Unity 6 and rebuilt in Unreal Engine 5: the same game in two engines.

  • Uni-Rate key art: the Uni-Rate mark beside the line “Real reviews, real students”, with two course-review cards floating alongside it - one in English and one in right-to-left Hebrew, each showing a star rating and an anonymous student's write-up.

  • Table Tennis Analyzer key art: an annotated rally frame with both players outlined in cyan and orange pose skeletons, the ball's flight traced across the table, heatmap panels for player coverage and ball positions, and a readout of the run's counts.

  • Teaching a Robot to Walk key art: three MuJoCo frames of a Unitree Go2 quadruped - the PPO champion mid-stride on the flat course, the genetic algorithm's champion pitching onto its nose, and the soccer policy standing over a yellow ball - beside the PPO reward curve and a readout of the run's training figures.

Working on something interesting?

Open to work: I am looking for a part-time student software engineering position alongside my degree, in any area of the stack, with the most depth in full-stack web, real-time 3D, and applied machine learning. Based in Ramat HaSharon, Israel, graduating October 2027, and I answer email fast.
