Software Engineer | iOS - Swift, UIKit, SwiftUI, Modular architecture | AWS Cloud | QA - Test Automation

I’m an iOS Developer with 5+ years of experience building and shipping production mobile apps using Swift, SwiftUI, and UIKit. I’ve worked across both product teams—most recently at Mercedes-Benz Mobility—and client-facing freelance projects, which has given me hands-on exposure to the full app lifecycle, from feature planning and architecture to testing, deployment, and iteration.

My core strength is building clean, modular iOS architectures (MVVM) with a strong focus on code quality, performance, and UX. I have solid experience with Core Data, REST APIs, and unit testing using XCTest, and I regularly work with CI/CD pipelines using tools like Fastlane and GitHub Actions to automate builds, testing, and releases.

Alongside mobile development, I’m actively strengthening my AWS Cloud Engineering skill set. I have hands-on experience with AWS fundamentals, including cloud infrastructure concepts, Linux environments, and CI/CD workflows, and I’m learning how to design and automate reliable pipelines that support mobile and backend systems. This cloud perspective helps me better understand scalability, deployment, and operational concerns beyond the app layer.

Earlier in my career, I worked as a QA Engineer testing mobile applications and embedded systems. That background still shapes how I write code today, I design features to be testable, resilient, and regression-safe, and I naturally think in terms of edge cases and failure scenarios.
