Hi, I’m Negar Rezaei, a senior iOS developer with 7+ years of experience designing and delivering high-quality mobile applications. I’m expert in Swift, UIKit, and SwiftUI, with a strong focus on clean architecture, performance optimization, and scalable mobile solutions. I have proven experience in API integration, asynchronous programming, testing, and CI/CD pipelines, and I enjoy collaborating with cross-functional teams including backend, product, and design. I also bring a solid background in backend systems, distributed architectures, and security‑focused software engineering, which helps me build robust mobile apps that work well with server-side components. I value code quality, refactoring, and best practices, and I take ownership of features from design to deployment.
