Husnain F.

Senior Mobile Engineer with 6+ years of expertise in building high-scale, crash-free applications. I don't just write code; I build mobile products that scale. Since 2019, I have transitioned from native Java and Kotlin to mastering Flutter and Swift, giving me a unique "Full-Stack Mobile" perspective that most developers lack. I understand the low-level native performance required for complex apps and the high-speed delivery of cross-platform solutions. ### Why work with me? • Seniority: 6+ years in the industry—I’ve seen the evolution of mobile and know how to avoid common architectural pitfalls. • The "Native" Edge: Unlike pure Flutter devs, my background in Kotlin and Swift allows me to write custom native plugins and optimize performance where others get stuck. • Reliability: I maintain a 99.9% crash-free rate and follow Clean Architecture (MVVM/Bloc) to ensure your code is maintainable for years. ### My Technical Arsenal: • Android: Kotlin, Java, Jetpack Compose, Coroutines, Dagger/Hilt. • Cross-Platform: Flutter (Dart), Bloc, Provider, GetX. • iOS: Swift, SwiftUI, Objective-C. • Backend & Tools: Firebase, REST APIs, GraphQL, CI/CD, App Store/Play Store Deployment. ### Specialized Services: • End-to-End App Development (MVP to Enterprise). • App Performance Audits & Bug Fixing. • AdMob & Mediation Optimization (Maximizing eCPM). • API Integration & Offline-First Database Architecture. I am looking for partners who value quality over the lowest price. If you want an app that users love and code that developers respect, let’s talk.
