👋 Hi, I'mGaurav SinghAndroid & KMP DeveloperI build cross-platform mobile apps with Kotlin Multiplatform and Jetpack Compose, focusing on clean UI and smooth user experiences. I’m also passionate about game development and enjoy creating gameplay systems in Unreal Engine and Godot.

🚀 About MeI’m a developer who loves building modern mobile apps using Kotlin Multiplatform, Jetpack Compose, Firebase, and custom REST APIs. I enjoy creating clean UI, improving user experience, and turning real ideas into apps that can go live on the Play Store. Along with app development, I’m also interested in game development and create gameplay systems, UI, and interactions using Unreal Engine (Blueprints) and Godot (GDScript). I use Figma for designing interfaces, build my own APIs when needed, and constantly explore new technologies to improve my work.
