With 10+ years of mobile development experience, I specialize in Swift, SwiftUI, Flutter, Firebase, REST APIs, app architecture, performance improvements, App Store releases, and integrating complex mobile features.
𝐈 𝐜𝐚𝐧 𝐡𝐞𝐥𝐩 𝐰𝐢𝐭𝐡:
𝐢𝐎𝐒 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭
• Swift / SwiftUI / UIKit / Objective-C
• MVVM, VIPER and Clean Architecture
• API and backend integration
• Firebase and push notifications
• Core Data / SQLite
• In-App Purchases and payment integrations
• Camera and media features
• Performance and crash troubleshooting
• App Store Connect and TestFlight
• Certificates, provisioning and release management
𝐅𝐥𝐮𝐭𝐭𝐞𝐫 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭
• Flutter / Dart
• iOS and Android applications
• Firebase integration
• REST API integration
• State management
• Existing Flutter application fixes and improvements
• Production builds and store releases
𝐄𝐱𝐢𝐬𝐭𝐢𝐧𝐠 𝐀𝐩𝐩 / 𝐋𝐞𝐠𝐚𝐜𝐲 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭
If you already have an application but are facing crashes, performance problems, outdated code, incomplete features, or difficult maintenance, I can first understand the existing codebase and then recommend the safest approach.
𝐓𝐡𝐢𝐬 𝐜𝐚𝐧 𝐢𝐧𝐜𝐥𝐮𝐝𝐞:
• Bug fixing and debugging
• Objective-C → Swift modernization
• Architecture improvements
• Performance optimization
• API integration
• UI/UX implementation
• Feature development
• App rebuilds and migrations
𝐀𝐩𝐩 𝐒𝐭𝐨𝐫𝐞 & 𝐑𝐞𝐥𝐞𝐚𝐬𝐞 𝐒𝐮𝐩𝐩𝐨𝐫𝐭
I can also help take an application from development to release, including:
• Xcode build configuration
• Signing and provisioning
• TestFlight
• App Store Connect
• App metadata preparation
• Privacy information
• Submission
• Review-related technical fixes
𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤
I don't believe every project needs a complicated architecture or unnecessary technology.
First, I understand what you already have, what is currently blocking you, and what the application needs next. Then I provide a practical implementation plan and work through the highest-priority items.
𝐘𝐨𝐮 𝐜𝐚𝐧 𝐞𝐱𝐩𝐞𝐜𝐭:
• Clear communication
• Practical technical recommendations
• Clean and maintainable code
• Attention to existing architecture
• Fast response
• Honest estimation
• Production-focused development
𝐌𝐲 𝐜𝐨𝐫𝐞 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬
Swift • SwiftUI • UIKit • Objective-C • Flutter • Dart • Xcode • Firebase • REST APIs • JSON • Core Data • SQLite • MVVM • VIPER • Clean Architecture • TestFlight • App Store Connect • Push Notifications • In-App Purchases • Payment Integration • CoreML • ARKit
I have worked on applications across social, community, content, marketplace, business and other product categories.
If you already have an app, send me the current situation, what is not working, and what you want to achieve.
If you're starting from an idea, send me the basic requirements and I can help you determine the right technical approach.
