ABOUT ME

Hi! I’m João, a programmer and game designer from Portugal.

I studied Electrical and Computer Engineering at Instituto Superior Técnico in Lisbon and began my career in AR/VR development. Then, I transitioned to video games, a long-time passion, building numerous prototypes along the way.

In 2023, I created The Fur in Me, a 2D platformer with color-based mechanics. Most recently, I launched A Tower’s Will, a 3D platformer about climbing a sentient tower.

I enjoy building both the technical and creative sides of games, from gameplay mechanics to polishing the final experience.
