Mobile Application Developer
Hi, I'm Srizan
Android native app developer with 4+ years of experience. Passionate about building robust, high-quality mobile applications. Skilled in Kotlin and Java for Android, and also experienced with Flutter for cross-platform development and exploring Kotlin Multiplatform (KMP) for sharing code across Android and iOS.
About Me
I started my journey in mobile development professionally over four years ago, driven by a fascination with how technology can improve everyday life. My expertise lies in building scalable, maintainable Android apps using Kotlin and Java.
I enjoy tackling complex challenges, collaborating with teams, and continuously learning new tools—like Flutter for cross-platform apps and Kotlin Multiplatform (KMP) to share code across Android and iOS. Outside of coding, I love sharing knowledge and exploring new tech trends.
