01. About Me

I'm an AI engineer who builds tools that make people's daily digital life smoother. My work sits at the intersection of language, AI, and culture.

Currently building Natively β€” an AI system keyboard that rewrites your Chinglish into natural English, instantly, in any app. Under the hood: LoRA fine-tuning to make models actually understand how bilingual people think.

I work across the full stack: Swift for iOS, Python for ML pipelines, JavaScript for tooling. VSCode is home base.

Technologies I work with

  • Swift / SwiftUI
  • Python / PyTorch
  • JavaScript / Node.js
  • LoRA Fine-tuning
  • iOS Keyboard Extensions
  • VSCode / Xcode

02. Things I've Built

Featured Project

Natively

Type in Chinese, sound like a native.

An AI system keyboard for iOS that rewrites your Chinglish into natural English, instantly, in any app. Type the way you think in Chinese, Chinglish, or a mix. Natively reads tone, slang, and context so you come across like a real person. Works everywhere β€” iMessage, WeChat, X, Discord, DMs.
