Expert iOS/Android Developer Swift/SwiftUI | Kotlin | Flutter Engineer

I’m a mobile app developer with 7+ years of experience building reliable, user-friendly applications for Android, iOS, and the web. I work mainly with Kotlin, Java, Swift, and PHP (Laravel), focusing on apps that are stable, scalable, and easy to maintain. I enjoy turning ideas into products that actually work well for users. From smooth UI and strong performance to clean backend logic, I care about building apps that feel simple to use but are solid under the hood. I also integrate AI-based features where they genuinely add value, such as smart search, recommendations, chat, or image/text recognition. I’ve worked across multiple domains and built features like payment gateways, scanners, digital signatures, real-time chat, push notifications, analytics, and social logins. I follow Material Design on Android and iOS to ensure a polished, native experience. 🔵 Skills & Experience 📱 Mobile Development ✅ Android: Kotlin, Java, Android SDK ✅ iOS: Swift, SwiftUI, UIKit ✅ KMM / cross-platform (when needed) 🌐 Web & Backend 🔹 PHP, Laravel, CodeIgniter, Node.js (APIs, admin panels, dashboards) 🔹 React.js, JavaScript, HTML, CSS 🔹 REST API design and integration 🤖 AI & Smart Features ✔ Recommendations & basic automation ✔ Chatbots & smart assistants ✔ OCR, scanning, image recognition ✔ ML Kit & TensorFlow Lite ✔ OpenAI & Google AI APIs 🛠 Tools & Integrations 🔹 Firebase (Auth, Firestore, Push, Analytics, Crashlytics) 🔹 Payments: Stripe, HyperPay, WorldPay 🔹 Git, Jira, Trello, Asana 💬 Click on “Message” and let’s connect. 📱 Have an app idea or need help improving an existing one? ✨ I’d love to discuss how we can bring your app to life with clean code and a great user experience.
