About

Hi, I’m Tien Chang Chiang (Charles). I’m a senior iOS and macOS engineer with 7+ years of experience delivering scalable, modularized, and secure applications for high-traffic platforms. I specialize in Swift, SwiftUI, MVVM-C, and Swift Package Manager, and I’ve maintained very low crash rates across 100k+ active users.

I love mentoring engineers, collaborating with security, backend, and design teams, and building robust architectures. I actively explore AI-assisted tooling (Cursor, Antigravity, Claude Code) to accelerate delivery while preserving quality.
