Profile: https://flows.cv/johnamoratis

iOS Senior/Staff engineer, SwiftUI builder, Apple Vision Pro expert. I specialize in all things iOS and Apple so that I can offer depth and experience. My work centers on clean architecture, performance, and long-term maintainability by turning complex codebases into modular, testable systems. I enjoy solving real engineering problems: debugging production issues, improving reliability, and shipping features. This is enriched by broad experience with DevOps, endpoint development, server administration, cross platform development, and web dev, allowing me to build systems end-to-end and collaborate effectively across teams.
