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. Since then: 🏅 Top Rated on Upwork ✅ 100% Job Success Score ⏱ 2k+ hours logged 🤝 Long-term client relationships ━━━━━━━━━━━━━━━━━━━━━━━ WHAT I CAN HELP YOU WITH ━━━━━━━━━━━━━━━━━━━━━━━ • iOS apps built with Swift & SwiftUI - scalable and App Store ready • Cross-platform apps using React Native (JavaScript/TypeScript) or Flutter • BLE & NFC integrations for IoT and hardware devices • Real-time features such as live streaming, chat, and location tracking • Stabilizing and refactoring poorly architected mobile apps • App Store & Google Play deployment, including rejection fixes ━━━━━━━━━━━━━━━━━━━━━━━ TECHNICAL EXPERTISE ━━━━━━━━━━━━━━━━━━━━━━━ iOS Development (11+ Years) • Swift, SwiftUI, UIKit, Objective-C • CoreBluetooth (BLE), CoreNFC • HealthKit, Apple Sign-In, OAuth • In-App Purchases & Subscriptions • Push Notifications (Firebase, OneSignal, Azure) React Native (6+ Years) • TypeScript, Redux, MobX, Redux-Toolkit • Native module bridging (iOS & Android) • Performance optimization & debugging • React Native upgrade to latest stable version Flutter (2+ Years) • Dart, GetX, Riverpod • Complex UI and API integrations API Integration & Mobile Tooling • REST & GraphQL API integration • Firebase services (Authentication, Messaging, Firestore), Supabase • Monitoring tools (Crashlytics, Sentry, Amplitude) • Mobile CI/CD pipelines (GitHub, GitLab, Bitbucket) • Agile collaboration (Jira, ClickUp, Monday) ━━━━━━━━━━━━━━━━━━━━━━━ INDUSTRIES I'VE BUILT APPS FOR ━━━━━━━━━━━━━━━━━━━━━━━ • Healthcare platforms (HIPAA-compliant systems) • IoT & hardware device communication • Dating & social networking platforms • Live streaming applications • Fitness & wellness apps • Ride-sharing and rental systems • Location-based apps using maps and geofencing ━━━━━━━━━━━━━━━━━━━━━━━ WHY CLIENTS WORK WITH ME LONG TERM ━━━━━━━━━━━━━━━━━━━━━━━ ✔ 11+ years of professional mobile engineering experience ✔ Clean architecture (MVVM, MVC, Clean Architecture) ✔ Consistent communication and daily progress updates ✔ Focus on product stability, scalability, and performance ✔ Engineering mindset, not just task execution ━━━━━━━━━━━━━━━━━━━━━━━ I work with a limited number of clients at a time so each project receives proper engineering attention rather than rushed freelance delivery. If you're building a mobile app, improving an existing one, or dealing with a complex codebase that needs to be stabilized or scaled, feel free to send an invite. I’ll review your requirements and respond with an honest technical assessment within 24 hours. Let's build something worth downloading.
