Profile Description

I’m ---------- , a Senior iOS Developer with over 10 years of experience building high-quality, commercial mobile applications for startups, established companies, and enterprise-level clients. My expertise spans Swift, SwiftUI, UIKit, async/await, Combine, MVVM, and clean architecture, allowing me to deliver fast, stable, and scalable apps that meet modern engineering standards.

I have extensive experience in:
• UI implementation using SwiftUI & UIKit
• API and backend integration
• CoreData and offline-first storage
• In-app purchases & RevenueCat setup
• Analytics and event tracking
• Bluetooth hardware features
• App Store deployment and TestFlight management

Beyond iOS, I also build cross-platform apps using Flutter and create AI-powered features, chatbots, and automation workflows using n8n + OpenAI. These help businesses streamline operations, improve customer experience, and grow faster with AI.

What I can help you with:
• Full iOS app development
• Feature/module development
• Refactoring & codebase improvements
• Flutter app development
• AI bot integration & workflow automation
• Product MVPs
• Long-term development & maintenance

I work with the latest Apple hardware (MacBook Pro M5, M1 Pro, Mac Mini) and test on real devices (iPhone 15 Pro, iPhone 17 Pro, latest iPad Pro, iPad Mini), ensuring smooth and accurate development.

I’m professional, detail-oriented, reliable, and family-oriented — I take every project seriously and communicate clearly.

If you’re looking for a high-level iOS developer who can deliver clean, maintainable, production-ready apps, I’d be happy to work with you.
