Levi Lei 雷子康

iOS engineer who ships, tests, and releases the whole thing.

I build iOS apps in Swift and Objective-C, and the TypeScript services behind them when that’s what the problem needs. Three years professional, based in Shanghai, most interested in modular architecture, testability, and release engineering that doesn’t depend on someone remembering a manual step.

  • ZKFloatingWindow

    A SwiftUI component for presenting floating windows — content that sits above the main app UI and stays visible while the user interacts with what is underneath. The goal is to make an overlay something you declare, not something you wire up per screen.
