About

Real-time VFX artist specializing in Unity VR/mobile optimization; shipped a Doctor Strange-inspired portal effect for a standalone Meta Quest 2 project ("Projeto Multiverso UNINASSAU") using a custom vertex-offset shader and carefully managed overdraw to hit 50+ FPS. Also building sci-fi VFX (explosions, lasers, environmental effects) for an in-development game ("Star Warfare") and uses AI tools to speed iteration, debugging, and documentation.
