I develop high-performance hybrid mobile applications that deliver reliable results in real-world environments, including Firebase integrations, push notifications, custom native plugins, and complex SDK integrations. With 14+ years of experience and over 200 successfully delivered projects, I specialize in building, optimizing, and maintaining Android and iOS applications using Ionic, Cordova, Capacitor, Vue.js, and React Native. I help businesses launch scalable, cost-effective mobile solutions and solve critical issues that other developers struggle to fix. My expertise includes app stabilization, performance optimization, native SDK integration, App Store compliance, and troubleshooting complex mobile application challenges. ### What I Can Do for You ✔ Develop cross-platform mobile applications (Android & iOS) from scratch ✔ Convert existing websites or web applications into mobile apps ✔ Develop custom Cordova and Capacitor plugins ✔ Integrate native iOS and Android SDKs into Ionic applications ✔ Diagnose and resolve crashes, bugs, and performance bottlenecks ✔ Upgrade legacy applications (Cordova → Capacitor migration) ✔ Integrate APIs, Firebase services, and third-party platforms ✔ Resolve App Store and Google Play review and deployment issues ✔ Optimize application speed, stability, and user experience ### Technical Expertise • Ionic Framework (Angular & Vue) • Apache Cordova & Capacitor • Vue.js & React Native • JavaScript, TypeScript, HTML5, CSS3 • Native Android (Java/Kotlin) • Native iOS (Swift/Objective-C) • Firebase (Authentication, Firestore, Analytics, Push Notifications) • REST APIs & Third-Party Integrations • WebView Optimization & Plugin Debugging ### Specialized SDK & Plugin Development • Custom Cordova Plugin Development • Custom Capacitor Plugin Development • Native SDK Bridging for Ionic Applications • Microblink BlinkID Integration • Passport, Driver's License & ID Card Scanning • Selfie Verification & Face Matching • OCR & Document Data Extraction • Barcode & QR Code Scanning • Camera & Media Processing Integrations • Biometric Authentication • Payment Gateway SDK Integrations • Push Notification SDK Integrations One of my key specialties is developing custom native plugins for Ionic, Cordova, and Capacitor applications. I have successfully built and integrated complex SDKs, including Microblink BlinkID, enabling passport scanning, driver's license scanning, ID card recognition, selfie matching, and OCR-based data extraction on both Android and iOS. When a required SDK does not have an existing plugin, I can build the complete native bridge and integration from scratch. ### Why Clients Work With Me • Strong expertise in solving complex mobile application issues • Advanced debugging skills across native and hybrid environments • Extensive experience with plugin development and SDK integrations • Clear communication and reliable delivery • Proven track record with production-grade and long-term projects If your application is experiencing crashes, performance issues, SDK integration challenges, App Store rejections, or deployment problems, I can quickly identify the root cause and implement a reliable solution. From concept → development → deployment → scaling, I manage the complete mobile application lifecycle. Available to start immediately.
