Hi there! Get in touch if you need an easy to work with and versatile lead/senior iOS developer for your app or platform that needs good performance, appealing user experience, and AI integration. I'm a developer and cofounder (indie game) specializing in graphics optimization (Metal/OpenGL), real-time visualizations, and embedding ML models for on-device inference. Experience with LLM fine-tuning, computer vision, and converting large models to compact on-device implementations. Led development of an App Store-featured app WikiNodes, and games with multiple awards. Recently built a word game using Metal shaders at 60fps, plus shipped computer vision features and cloud-based agent architectures.

Seeking remote senior/lead role.
