About

Real-time VFX/shader artist with hands-on experience shipping optimized effects for both mobile and VR in Unity. Built a time-of-day skybox shader driven by a single variable and optimized it using precomputed RGBA noise textures from Substance Designer; also created a VR shield effect designed to stay performant in a vegetation-heavy, overdraw-prone environment.

Key Strengths

• Builds parameter-driven shaders (single time-of-day variable controlling multiple skybox properties)
• Mobile-focused shader optimization via precomputed textures and minimal exposed parameters
• VR VFX optimization in overdraw-heavy scenes (vegetation) while maintaining visual quality
• Efficient asset reuse and low-resolution/packed textures to reduce GPU cost
• Uses profiling signals (draw calls, batches, overdraw, GPU/CPU) to guide optimization
