Achmad Rijalu

Mobile Engineer | iOS & Cross-Platform Developer

Hello! You can call me Rijalu. I am an iOS Developer passionate about building apps with seamless best practices.

Born in 2002 in Surabaya, my journey into mobile development began with Flutter, where I spent two years crafting applications. In 2023, I shifted my focus to iOS development, diving deep into UIKit and SwiftUI after joining the Apple Developer Academy. My learning continued in 2024 through the Apple Catalyst Program, where I honed my expertise in creating scalable and efficient iOS applications.

Currently, I'm exploring The Composable Architecture (TCA) while leveraging established patterns like MVC, MVVM, and VIPER.
