Demian N.

Senior iOS Graphics Engineer — Metal, Camera Apps & Creative Tools I help camera, AI, and creative iOS apps turn complex visual prototypes into stable, production-ready features. My work focuses on native iOS graphics, real-time camera pipelines, GPU rendering, and high-performance image processing. I have production experience with Metal, OpenGL, AVFoundation, Core Image, OpenCV, shader-based UI, LUT/preset systems, IAP/RevenueCat, TestFlight, and App Store release support. I’m comfortable owning the full delivery path: architecture, rendering, performance, integration, debugging, and polish. Typical projects I can help with include custom Metal effects, camera/image processing pipelines, shader-driven UI, WebGL/Figma/After Effects prototype conversion to native iOS, performance optimization, and production cleanup for creative mobile apps. I’m strongest when the product has a bold visual idea and needs an engineer who can make it fast, reliable, and shippable.
