HI, I AM
RYAN VIERI KWA.
An iOS developer based who loves crafting smooth, accessible, and delightful mobile apps.
Hi, I'm Ryan — an iOS Developer who loves crafting intuitive, scalable, and user-focused mobile experiences
I specialize in Swift, UIKit, and architectures like VIPER and MVVM, along with reactive patterns using RxSwift. Over the years, I've built high-impact features and contributed to large-scale ecosystems. I care deeply about code quality, clean architecture, and performance — supported by experience with unit testing, CI/CD pipelines, and Agile workflows. Lately, I've been exploring SwiftUI to broaden my approach to building interfaces and keep up with the evolving iOS ecosystem.
I've worked across banking and financial products, building secure and reliable applications used by millions of users. I enjoy transforming complex requirements into smooth, accessible, and meaningful user experiences. My background in Computer Science and training from Apple Developer Academy @BINUS help me approach problems with structure, curiosity, and a strong product mindset.
Besides coding, I find myself enjoying reading about books, exploring meta(most effective tactic) in games and trying out new things — whether it's improving problem solving skills, exploring new tools, or picking up hobbies that keep me inspired. For me, great engineering is a blend of creativity, precision, and continuous refinement — much like mastering a game strategy.
