Senior Mobile App Developer specializing in iOS (Objective-C/Swift/SwiftUI), React Native and Flutter with 11+ years of experience building production-grade mobile applications. I help startups and product teams to build scalable apps, integrate complex features, and ship reliable releases to the App Store and Google Play Store. Before full-time freelancing, I spent 9 years as a full-time mobile engineer - growing from Junior iOS Developer to Senior iOS and React Native Developer at a product-focused software company. I wasn't job-hopping. I was building. During those years I worked on real production apps, made architectural decisions, integrated hardware devices, and solved the kind of problems that appear only after an app reaches real users. In 2023 I moved into freelancing with one goal: bring the same engineering discipline and product mindset to companies that want more than average freelance work.
