About Me

Guillem Serra

I'm Guillem Serra, a video game programmer with over 6 years of professional experience.

I build systems with scalability in mind, whether it's gameplay mechanics, editor tools, UI logic, or procedural generation; designed to boost team productivity and enhance the player experience. My goal is to turn design intent into expressive, efficient, and maintainable code.

I'm driven by passion for my craft and a constant desire to learn and grow, both individually and alongside my team. I thrive where technical challenges meet artistic ambition.
