Hire the Best Firebase Developers
in Malaysia

I’m an experienced Mobile Engineer & Team Lead with 11+ years of expertise in Android and iOS development, delivering apps that have reached millions of users worldwide. Over the years, I’ve built, scaled, and maintained enterprise-grade apps as well as specialized custom solutions, with a strong focus on performance, clean architecture, and modern mobile best practices. What I Do Best: Mobile Development (Android & iOS) – Expert in Android (Kotlin/Java) and experienced in iOS (Swift/SwiftUI), building high-quality, production-ready applications across both platforms. Strong knowledge of Jetpack, coroutines, Hilt/Dagger, Room, Navigation, RxJava, Firebase, and App Store / Play Store guidelines. App Architecture & Performance – Scalable MVVM/MVI architectures, optimized UI patterns (RecyclerView, ViewPager2), efficient state management, robust caching, and offline-first strategies. Authentication & Security – OAuth2, token refresh flows, secure storage, deep linking (Branch), push notifications (FCM/APNs), and analytics integrations (MoEngage, Firebase). Team Leadership – Currently serving as Engineering Lead (Mobile), mentoring developers, driving architecture decisions, and ensuring delivery under tight timelines. What You Can Expect: ✔️ Fast & reliable delivery – I prioritize hitting deadlines without compromising quality. ✔️ Clear communication – Regular updates, proactive suggestions, and collaborative problem-solving. ✔️ Long-term value – I don’t just build apps; I help you plan for scale, stability, and future growth. ✔️ Hands-on expertise – Whether fixing urgent production crashes, building new features, or leading full app development, I take ownership until the job is done right.
