Summary: iOS engineer with 15+ years building consumer mobile products used by millions. I specialize in crafting responsive, high-polish UI, scalable mobile architecture, and rapid experimentation (feature flags + analytics) to ship and iterate quickly. I’m especially interested in AI-driven interaction patterns on mobile: streaming responses, context management, trust, and “simple but powerful” UX.
