I'm Hussain Gaddal. Senior Android Developer.

I build apps that just work — large-scale, multi-platform, and built to last. My work bridges clean system architecture with native mobile performance using Kotlin Multiplatform.

About Me

Building the Intersection of Systems and UX.

Based in Riyadh at Kay Technology, I lead the development of large, multi-module Android applications, driving architecture improvements and product reliability. I focus on Clean Architecture, Unidirectional Data Flow (MVI/MVVM), and high testing standards.

My current work explores the capabilities of Compose Multiplatform (CMP) and building reliable backend services using Ktor, connecting full-stack systems with fast native mobile apps.

Beyond the IDE, I spend my time exploring 3D Printing, listening to tech podcasts, and improving my programming skills.
