Gustavo Amaral

I'm a Software Engineer with 5+ years of experience working on global projects, international teams, and large-scale applications such as CNN, which serves 6M+ monthly active users. I specialize in iOS development with Swift, SwiftUI, and UIKit, focusing on creating scalable, high-performance, and user-friendly mobile applications that deliver strong user experiences. Alongside my iOS expertise, I also work with modern concurrency, reactive programming, and mobile architectures such as MVVM, VIPER, MVC, Dependency Injection, and Modular Architecture. Throughout my career, I've contributed to mobile platforms serving 6M+ monthly active users, building core features, improving app quality, and supporting reliable releases. Key achievements include developing high-impact features for large-scale applications, working with async/await and Combine to modernize codebases, improving testability through unit and UI testing, and using tools like Firebase Crashlytics, XCTest, XCUITest, Optimizely, GitHub Copilot, and Cursor to improve debugging, code reviews, and delivery speed. My initial background came from the Apple Developer Academy, where I learned how to be proactive, self-unblocking, and solution-oriented. I also bring experience with CI/CD, Fastlane, Bitrise, REST APIs, Firebase, AWS, GCP, and mobile networking, which helps me build applications that are both polished for users and reliable in production. My goal is to keep growing as an iOS Software Engineer while working on meaningful products that combine technical excellence, business value, and real impact at scale.

•Engineered core features for a global news application with 6M+ users, including high-traffic election-related functionality and real-time updates.

• Architected scalable UI components and screens using SwiftUI.

• Refactored experimentation framework by improving Optimizely Feature Flags and A/B testing infrastructure to drive data-informed product decisions.

• Enhanced App Store presence by implementing "Liquid Glass" UI/UX improvements, directly increasing application visibility and engagement.
