About Me
Building production-ready mobile solutions with modern architectures.
I'm a Computer Engineering graduate and Junior Mobile Application Developer with hands-on experience building production systems at Journeytech Inc. I specialize in native Android development using Kotlin and Jetpack Compose, with proven expertise in implementing complex features like real-time data syncing, REST API integration, and inter-app communication through AIDL.
I'm passionate about writing clean code, applying MVVM and MVI architectural patterns, and continuously learning the latest mobile development practices. With experience in both backend (Java, REST APIs) and frontend (Jetpack Compose, XML layouts) development, I deliver high-quality, scalable applications.
