Hi, I'm Nico Marcelino. I'm a game programmer with a Computer Science background, primarily building games and systems in **Unity (C#)**.

I focus on building responsive player controls, solid gameplay systems, polished user interfaces (UI), and clean, modular code that is easy to iterate on. I like building mechanics from scratch, testing ideas quickly through prototypes, and finding the right balance between clean architecture and practical execution.
