I’m Juan Sebastián Cadavid, a Medellín-based game developer who turns bold ideas into polished play. In just under two years I’ve shipped titles such as UPB Runners, a Roblox hit for Brandcade, and Connect 4 by Hasbro inside Fortnite’s UEFN. Fluent in C#, C++, Lua and at home in Unity, UE5, Roblox Studio and UEFN, I specialize in physics-driven mechanics and performance optimization, blending solid engineering (SOLID principles, clean architecture) with creative flair. Whether leading a small team or freelancing solo, I thrive on transforming concepts into unforgettable, technically-sound experiences—and I’m always hungry for the next challenge in games or augmented reality.

    paper UPB Runners

    UPB Runners is an endless runner made in Unity 3D, fully programmed by me. This project highlights my skills in C#, where I developed a custom-built player controller with smooth and realistic animations. I manually created the physics to ensure precise and engaging gameplay.

    In addition to the core mechanics, I focused extensively on optimization and lighting. These efforts improved the game’s performance and visual appeal, demonstrating my ability to enhance both functionality and aesthetics.

    UPB Runners showcases my technical skills and ability to handle complex game development tasks independently. From scripting and physics to optimization and lighting, this project reflects my comprehensive skill set and dedication to creating high-quality, polished games.
